Synopsis

Fig (Ficus carica L.): A Comprehensive Reference

1. Identity, Botanical Classification, and Common Forms

Taxonomy and Nomenclature

Fig is botanically called Ficus carica L. and belongs to the mulberry family, Moraceae. The fig species of greatest commercial importance is Ficus carica L. (syn. Ficus kopetdagensis Pachom.), also known as the common fig, which consists of numerous varieties with significant genetic diversity. The genus Ficus (Moraceae) constitutes one of the largest genera of angiosperms, with more than 800 species of trees, epiphytes, and shrubs found in tropical and subtropical regions worldwide.

Botanical Description and Origin

Ficus carica is a deciduous shrub or tree popularly called Fig. It grows well in warm climates, particularly in the Mediterranean region, Western Asia, and India. It is part of the Moraceae (mulberry) family, in which its medicinal properties extend not only to the fruits but also to the leaves, bark, and latex. It originated in the Middle East and western Asia and is one of the earliest fruit crops domesticated by mankind. F. carica is reported to be one of the oldest tree crops and medicinal plants used by humans; archaeological evidence has suggested that it has been cultivated for over 11,000 years, possibly predating cereal grains.

Botanically, the fig fruit is called a syconium. The edible fig species contains latex in parenchyma cells. The fig is characterized by its distinctive syconium structure, which arises from the development of numerous small flowers encased within a fleshy receptacle—a notable feature in plant morphology.

Common Forms and Preparations

Fruits are readily available on the market for consumption in fresh or dried forms and are regarded as a unique source of fiber and phenolics, particularly furanocoumarins, proanthocyanidins, and phenolic acids. Ficus carica's different parts—pulp, leaves, seeds, peels, and latex—can be used for various purposes, with peels and leaves being the main parts used medicinally. In commerce and research, fig preparations include: fresh fruit, dried fruit, fruit paste, fruit extract, leaf decoction or tea, leaf extract (aqueous, methanolic, or ethyl acetate), and raw latex from the tree. Industrially, Ficus carica latex is used as an alternative to animal enzymes in milk clotting for cheese production, meat tenderization, bioactive peptide production, and natural rubber production.

2. Traditional and Historical Use

Ancient and Cross-Cultural Use

Since early in human history, the common fig was appreciated as food and for its medicinal properties. A review of the medicinal uses of figs for potential cancer and diseases with cancer-related etiologies includes ancient, medieval, and early modern herbals from the Middle East and Europe. These texts cover the period from the 1st century CE to the 17th century, and geographically cover the area from Persia to Spain and from North Africa to England and Germany.

Fig (Ficus carica) tree latex was a source of treatment of different diseases in Iranian traditional medicine, as reported by Avicenna in his 10th century Canon of Medicine. Traditional methods of preparing fig medicaments include fig lye, fig wine, and medicinal poultices.

Traditional Systems of Medicine

A number of Ficus species are used as food and for medicinal properties in Ayurvedic and traditional Chinese medicine, especially among people who live in regions where these species grow. The therapeutic utilities of F. carica have been indicated in traditional systems of medicine such as Ayurveda, Unani, and Siddha. It has been used to treat disorders of the endocrine system (diabetes), the respiratory system (liver diseases, asthma, and cough), the gastrointestinal tract (ulcers and vomiting), the reproductive system (menstruation pain), and infectious diseases (skin disease, scabies, and gonorrhea). Figs are also part of traditional Chinese, Siddha, and Ayurvedic medicine, addressing gastrointestinal, respiratory, and cardiovascular ailments.

Unani medical texts report that F. carica can alleviate constipation, dysentery, enteritis, and haemorrhoids, and also acts as a laxative, purgative, antipyretic, and aphrodisiac. In the Mediterranean region, fig is so widely used—both fresh and dried—that it is called "the poor man's food." The plant has been used in traditional medicine for a wide range of ailments related to the digestive, endocrine, reproductive, and respiratory systems, and also for cancer.

Ethnobotanical Documentation

A survey aimed to define the ethnobotanical uses of the fig tree in southern Italy (Campania and Basilicata) collected field data during the periods 2000–2014 through structured interviews. The results showed a high number of traditional uses of the fig tree in medicine, human and animal nutrition, and domestic-handicraft purposes. The plant parts most frequently used were syconia (the fruit). The majority of the medicinal uses of figs in humans are based on historical reports or anecdotal evidence, with only a few reports coming from modern clinical trials.

3. Nutritional Composition

Macronutrient Profile

Per 100 grams of fresh fig, the nutritional composition includes water (79.1 g), energy (310 kJ), carbohydrates (19.2 g), sugars (16.3 g), dietary fiber (2.9 g), total fat (0.3 g), and protein (0.7 g). Fig is a high-carbohydrate fruit and a good source of dietary fiber. The carbohydrate content of fresh fig is 19.2 g per 100 g of fresh fruit weight. About 92% of the carbohydrates in fig are in the form of sugars. Glucose, fructose, and sucrose are the main sugars present in the fruit.

Micronutrient Profile (Fresh Fruit per 100 g, USDA Data)

Micronutrients present in fresh fig include: Vitamin A (142 IU), Thiamine B1 (0.1 mg), Riboflavin B2 (0.1 mg), Niacin B3 (0.4 mg), Pantothenic acid B5 (0.3 mg), Vitamin B6 (0.1 mg), Folate B9 (6 mcg), Vitamin C (2 mg), Vitamin E (0.1 mg), Vitamin K (4.7 mcg), Calcium (35 mg), Iron (0.4 mg), Magnesium (17 mg), Manganese (0.1 mg), Phosphorus (14 mg), Potassium (232 mg), Sodium (1 mg), and Zinc (0.2 mg), based on data from the USDA National Nutrient Database.

Among the minerals, calcium (Ca) is the most abundant in fig seeds and leaves, while in fig fruits, potassium (K) is found in the highest concentration. Other minerals such as magnesium (Mg), sodium (Na), and phosphorus (P), as well as zinc (Zn), manganese (Mn), copper (Cu), and iron (Fe), are also present in varying amounts.

Dried Figs

In a 100-gram serving providing 249 calories, dried figs are a rich source (more than 20% DV) of dietary fiber and the essential mineral manganese (26% DV), while calcium, iron, magnesium, potassium, and vitamin K are in moderate amounts. Dried figs are excellent sources of minerals like calcium, copper, potassium, manganese, iron, selenium, and zinc. 100 g of dried figs contain 680 mg of potassium, 162 mg of calcium, and 2.03 mg of iron.

4. Key Phytochemical Constituents and Active Compounds

Overview of Chemical Classes

Phytochemical research carried out on Ficus carica has led to the isolation of phytosterols, anthocyanins, amino acids, organic acids, fatty acids, phenolic components, hydrocarbons, aliphatic alcohols, volatile components, and a few other classes of secondary metabolites from its different parts. Numerous bioactive compounds—such as phenolic compounds (phenolic acids), flavonoids (flavonols, flavones, and anthocyanins), coumarins, sterols, and volatiles (monoterpenes, sesquiterpenes, norisoprenoids, ketones, alcohols, and esters)—have been reported. Ficus carica L. is a native plant to Southwest Asia and widely spread from ancient times in the Mediterranean region. Its fruits and leaves present important nutritional components (vitamins, minerals, sugars, and amino acids) as well as health-related effects due to their phytochemical composition.

Phenolic Compounds and Flavonoids

Phytochemical studies on the leaves and fruits of the plant have shown that they are rich in phenolics, organic acids, and volatile compounds. The composition of phenylpropanoids (polyphenols and furanocoumarins) has been determined in the leaves of 37 cultivars of fig. The most abundant polyphenol was caffeoylmalic acid. Phytochemical components in F. carica include flavonoids, alkaloids, coumarins, triterpenoids, saponins, and phenolic compounds.

Furanocoumarins

Ficin, bergapten, and psoralen are some of the major bioactive compounds found in figs. Many fig varieties are known to contain furanocoumarins, such as psoralen and bergapten. These compounds are biologically active but also carry phototoxic risks (discussed in the Safety section).

Organic Acids

The organic acid profile of fig leaves is composed of six organic acids: oxalic, citric, malic, quinic, shikimic, and fumaric acids.

Latex and the Ficin Enzyme

Ficus carica latex contains metabolites including proteins, minerals, vitamins, antioxidants, phenolics, terpenoids, sterols, volatile components, fatty acids, amino acids, and proteases. Most latex pharmacological activities are attributed to its phenolic contents, including flavonoids, coumarins, xanthones, and phenolic acids. Moreover, Ficus carica latex contains many enzyme activities such as proteases and chitinase enzymes involved in antiparasitic, antimicrobial, and anticancer activities. The ficin enzyme from fig latex has protease and peroxidase activities and is linked to cancer research.

Anticancer-Relevant Compounds

One group of active compounds, 6-O-acyl-β-d-glucosyl-β-sitosterols, found in F. carica latex, has been specifically linked to anticancer activity. GC-MS analysis of fig extracts has identified terpenes, sterols, and fatty acids as major constituents.

Anthocyanins

Total phenol, flavonoid, and anthocyanin content have been reported and vary by cultivar; the San Francesco cultivar is characterised by the highest phenol and flavonoid content, while Dottato showed the major anthocyanin content.

5. Pharmacological Mechanisms of Action

Antioxidant Activity

Ficus carica is characterised by a good profile of bioactive constituents—polyphenols, flavonoids, anthocyanins, coumarins, and organic acids—that provide it with strong antioxidant, anti-inflammatory, and antimicrobial effects. Polyphenols are plant secondary metabolites with antioxidant properties that serve as free radical inhibitors and play essential roles in reducing oxidative stress.

Anti-inflammatory Mechanisms

In addition to their phytochemical profile, Ficus carica preparations possess remarkable pharmacological properties including antioxidant, anticancer, cytotoxic, anti-inflammatory, and hypolipidemic activities. The anti-inflammatory action is attributed primarily to phenolic fractions, which modulate inflammatory signaling pathways, though the precise human-validated mechanisms remain under investigation.

Laxative and Gastrointestinal Mechanisms

The beneficial effects of F. carica paste on constipation are most likely related to its composition: F. carica contains high amounts of cellulose, phenols, flavonoids, and anthocyanins, which are reported to have laxative effects. In rat studies, fig extracts or pastes demonstrated laxative effects and enhanced physical bowel movement, as shown by increased fecal pellet number, weight, and water content in fig paste-treated animals compared to non-treated animals.

Hypoglycaemic Mechanisms

The hypoglycemic effect of an aqueous extract of Ficus carica leaves was studied in streptozotocin-diabetic rats. The extract induced a significant hypoglycemic effect after either oral or intraperitoneal administration. Body weight loss was prevented in treated diabetic rats and the survival index was significantly affected by plasma insulin levels. Results showed that Ficus carica aqueous extract has a clear hypoglycemic activity in treated versus non-treated diabetic rats. The mechanism involved in such an effect has not been fully elucidated.

Anticancer Mechanisms (Preclinical)

Most latex pharmacological activities are attributed to its phenolic contents, including flavonoids, coumarins, xanthones, and phenolic acids. Moreover, Ficus carica latex contains many enzyme activities such as proteases and chitinase enzymes involved in antiparasitic, antimicrobial, and anticancer activities. Latex extracts of Ficus carica have been shown to contain strong anti-angiogenic and anti-proliferative activities in experimental (non-human) models.

6. Scientific Evidence by Area of Use

6.1 Digestive Health and Constipation

Ficus carica fruit has been traditionally used for its medicinal benefits, including improvement of the digestive system, treatment of constipation, and use as a natural laxative.

Human/Clinical Evidence:

A placebo-controlled trial of fig paste in 80 patients with chronic constipation demonstrated reduced colonic transit time and significant improvements in abdominal discomfort and stool form. The design of this randomized, double-blind study is described further: investigators performed an 8-week, randomized, double-blind, placebo-controlled human trial to evaluate the efficacy and safety of fig paste on functional constipation, measuring colon transit time, frequency of defecation, defecation time, stool type, and abdominal discomfort.

A clinical trial registered at ClinicalTrials.gov (NCT02559245) evaluated the effect of Ficus carica and Descurainia Sophia on irritable bowel syndrome with predominant constipation, with one-third of patients receiving Ficus carica, another third receiving Descurainia Sophia, and the remainder following their regular diet for 4 months.

Evidence Strength: The in vivo and in vitro evidence is significant, but clinical validation is still insufficient because different extraction techniques, different plant parts, phytochemical standardization, and dosage schedules cause variations. The majority of the available information comes from preclinical models and requires controlled human trials to shed light on mechanisms, bioavailability, and safety profiles. The constipation area has the most direct human trial support among all therapeutic applications of fig.

6.2 Blood Glucose Regulation / Diabetes

Animal Evidence:

The ethyl acetate extract (250 and 500 mg/kg) of F. carica leaves showed a significant effect (p < 0.005) in the levels of blood glucose, total cholesterol (TC), triglycerides (TG), body weight, and hepatic glycogen in type 2 diabetic rats. Diabetes was induced by a single dose of alloxan monohydrate (65 mg/kg body weight), and diabetic rats were treated with a dose of 200 mg/kg body weight of the methanolic extracts of Ficus carica leaves or buds or their combination for 30 days, with blood sugar and body weight measured throughout.

Human/Clinical Evidence:

A double-blind crossover clinical trial aimed to evaluate hypoglycemic effects of Ficus carica (FC) decoction (common fig leaf) in patients with type 2 DM. There were two groups of 14 subjects. During the first phase of the study, one group received fig leaf decoction for 21 days and the other one received green tea as placebo. After a one-week washout period, the patients changed their medications and continued for another 21 days. Variables including fasting blood sugar (FBS), 2-hour postprandial blood sugar (2hpp), fructosamine, HbA1c, C-peptide, AST, and ALT were analyzed. Thirteen patients in each group completed the trial. Results showed that fig leaf decoction could significantly decrease the 2-hour postprandial blood glucose (2hpp) in patients with type 2 DM (P < 0.001), but it could not change patients' fasting blood sugar (FBS) or fructosamine levels.

Earlier research on the hypoglycemic effect of F. carica was limited to one study on rats with diabetes and another study on 10 insulin-dependent humans.

Evidence Strength: Evidence for blood glucose lowering is promising but preliminary. Animal data are consistent; human data are very limited in sample size, and findings are partial (e.g., only postprandial glucose, not fasting glucose, was significantly reduced in the crossover trial). Larger, well-controlled human clinical trials are needed.

6.3 Skin Conditions — Atopic Dermatitis

Topical Fruit Extract (Pediatric):

Safety, efficacy, tolerability, and symptom relief were considerable for fig fruit extract in comparison with hydrocortisone 1.0%. This clinical trial suggests that fig fruit extract can be used instead of low-potency corticosteroids in mild to moderate atopic dermatitis.

Oral Fig Leaf Tea (Adults):

In a double-blind, randomized, placebo-controlled preliminary trial, the study period was 12 weeks (8-week intervention period and a 4-week non-intervention observation period). During the intervention period, participants were asked to ingest 500 mL of either fig leaf tea or a placebo daily. This clinical study showed that the consumption of fig leaf tea significantly improved skin symptoms in patients with mild atopic dermatitis. There were no significant differences in the levels of other blood components in the two groups, suggesting that fig leaf tea without furanocoumarin does not cause serious side effects in the range of commonly measured blood constituents.

Evidence Strength: Preliminary. Both studies are small, relatively short-term, and described as pilot or preliminary trials. Results are encouraging but not sufficient to make firm clinical recommendations.

6.4 Skin Conditions — Warts

A clinical trial involving 25 participants demonstrated that fig latex resulted in 44% complete clearance of warts, whereas cryotherapy achieved a 56% success rate. Notably, fig latex users reported no adverse reactions.

Evidence Strength: Very preliminary; single small trial only. The comparator (cryotherapy) outperformed fig latex in clearance rate. Results do not support fig latex as a superior alternative but indicate comparable and tolerable activity.

6.5 Lipid Metabolism

Pérez et al. (1999) investigated the hypolipidemic effect of intraperitoneal administration of a Ficus carica leaf decoction. The plasma total cholesterol levels showed clearly positive results indicating the presence in the fig leaf decoction of a compound or compounds that influence lipid metabolism. Some studies have reported therapeutic effects of decoction of Ficus carica leaves on lipid and antioxidant profiles of patients with diabetes.

Evidence Strength: Weak for humans. Most data are from animal or in vitro models. The human lipid data arise primarily from diabetic populations receiving decoctions rather than from dedicated lipid intervention trials.

6.6 Anticancer Activity

Experimental studies have shown that latex from F. carica can inhibit the growth of various cancer cells. One group of active compounds, 6-O-acyl-β-d-glucosyl-β-sitosterols found in F. carica latex, has been specifically linked to this anticancer activity. In a 2011 study, Khodarahmi et al. reported that fig latex and extracts could trigger the death of HeLa cells, a type of cervical cancer, and highlighted the potential of fig latex in the management of human papillomavirus-related cervical cancer.

Ficus species exhibit significant anticancer and anti-inflammatory activities, supported by historical and modern uses. Phytochemical compounds from Ficus, such as phenanthroindolizidine alkaloids, show potent cytotoxic effects on cancer cell lines.

Evidence Strength: Entirely preclinical (in vitro and animal). No human clinical trials have confirmed anticancer efficacy of fig preparations. These findings are mechanistically interesting but cannot be extrapolated to therapeutic recommendations for humans.

6.7 Antimicrobial Activity

Anticancer, antiviral, antimicrobial, antihypertensive, antiparasitic, anticoagulant, anti-inflammatory, antioxidant, anti-angiogenic, and hepatoprotective activities are pharmacologically reported for Ficus carica latex. Antimicrobial activity has been confirmed in vitro against resistant human pathogens using latex fractions, but clinical validation remains insufficient because of variations in extraction techniques, plant parts, phytochemical standardization, and dosage schedules.

Evidence Strength: Weak. Antimicrobial evidence is almost entirely from in vitro (laboratory) experiments; no clinical trials in humans have been conducted.

6.8 Hepatoprotective Activity

Animal studies have shown a remarkable hepatoprotective effect of Ficus carica leaf and bud extracts and their combination in diabetic-treated groups, by reducing the release of transaminase enzymes. This effect was similar to that observed in previous in vivo hepatoprotective studies showing that Ficus carica leaf extract could reverse liver injury induced by different agents. Blood levels of aspartate aminotransferase (AST) and lactate dehydrogenase (LDH), which are indicators of liver disease, were significantly reduced in patients who consumed fig leaf tea in one preliminary human trial.

Evidence Strength: Primarily preclinical; the one human observation derives from a small atopic dermatitis trial as a secondary finding. Dedicated human hepatoprotective trials do not yet exist.

7. Body Systems and Health Areas Associated with Fig

Gastrointestinal system: Figs are used in traditional medicine as a natural laxative and to treat numerous disorders such as gastrointestinal colic, indigestion, constipation, and loss of appetite.
Endocrine / metabolic: Hypoglycemic effects documented in animal models; partial evidence in human type 2 diabetes; effects on lipid profiles in preclinical models.
Dermatology: Topical use for atopic dermatitis (fruit extract and leaf tea), wart clearance (latex), and traditional use for skin diseases.
Cardiovascular: Existing evidence demonstrates positive impact on lipid metabolism and cardiovascular protection in preclinical studies. Magnesium, present in figs, is considered essential for preventing cardiovascular disorders.
Musculoskeletal / bone health: Minerals including strontium (Sr), calcium (Ca), magnesium (Mg), phosphorus (Ph), and iron (Fe) are abundant in figs. According to studies, calcium helps reduce osteoporosis and the accompanying fractures.
Oncology (preclinical only): Anticancer and anti-angiogenic effects reported in in vitro and animal models.
Antimicrobial / immune: In vitro antimicrobial and antiparasitic activity attributed to latex enzymes and phenolics.
Hepatic: Hepatoprotective effects in animal models; preliminary signal in one human study.

8. Dosage Forms and Dosages Reported in Studies

The following dosages are cited only as they appear in the source research literature and are not recommendations:

Fig paste (oral, constipation): An 8-week, randomized, double-blind, placebo-controlled human trial evaluated the efficacy and safety of fig paste on functional constipation in 80 participants.
Fig leaf decoction (oral, type 2 diabetes): One group received fig leaf decoction for 21 days, followed by a one-week washout period, then another 21 days of the alternate preparation, in a crossover design.
Fig leaf tea (oral, atopic dermatitis): The study period was 12 weeks (8-week intervention and 4-week observation). During the intervention period, participants were asked to ingest 500 mL of either fig leaf tea or a placebo daily.
Fig leaf extract (animal, diabetes): The ethyl acetate extract at doses of 250 and 500 mg/kg of F. carica leaves was administered for 28 days in rats.
Methanolic leaf/bud extract (animal, diabetes): Diabetic rats were treated with a dose of 200 mg/kg body weight of the methanolic extracts of Ficus carica leaves or buds or their combination for 30 days.
Ficin / fig latex (in vitro, cancer cells): Cells were treated with various concentrations of ficin (60, 70, 80, and 100 mg L⁻¹) or fig latices (10, 20, 30, and 40 mg L⁻¹) for up to 72 hours.

No standardized or consensus dosage for any therapeutic application in humans has been established by regulatory or official pharmacopoeial bodies as of the time of this writing. Variations in extraction techniques, different plant parts, phytochemical standardization, and dosage schedules remain a central challenge to clinical translation.

9. Safety Considerations and Interactions

Phototoxicity and Photocontact Dermatitis

Many fig varieties are known to contain furanocoumarins, such as psoralen and bergapten. Psoralen is known to be phototoxic, increasing the effects of UV light, and cases of erythematous and edematous rashes have been reported upon treatment with fig leaves. Fig latex causes skin irritation and phototoxicity. Despite its medicinal benefits, fig latex can cause skin irritation and reactions to sunlight, which is known as phytophotodermatitis.

Potential CYP3A4 Drug Interaction

It has been reported that furanocoumarin in grapefruit inhibits the activity of the drug-metabolizing enzyme CYP3A4. The potential of furanocoumarin in figs to interact with drugs is high, and caution should be exercised when consuming fig leaf preparations containing furanocoumarin.

Allergic Reactions

Ficus carica is an edible fruit belonging to the Moraceae family and is rarely described as a cause of food allergy. Cases of fig allergy reported in the literature have been related to cross-sensitization to weeping fig (Ficus benjamina), a common ornamental houseplant, or could be included in the context of "latex-fruit syndrome" or "ficus-fruit syndrome." The ficin enzyme, the major fig allergen, belongs to the cysteine protease family, similar to the dust mite allergen Der p 1; cross-reactivity between these two proteins, which present structural homology, has been reported.

Allergic anaphylactic reactions to fig fruit are scarcely reported. Nevertheless, one case series documented: a 10-year-old girl experienced oral allergy syndrome, drooling, urticaria, lip and face angioedema, and dyspnea after ingestion of a fresh fig, and was treated in the emergency room with inhaled salbutamol and intravenous antihistamines and corticosteroids, showing progressive improvement.

Oxalate Content

Oxalates are natural compounds that can bind with calcium in the body and form crystals. For most people, this is not a problem. However, for individuals who are susceptible to forming calcium oxalate kidney stones, a high intake of oxalate-rich foods like figs can increase the risk of stone formation. Therefore, people with a history of kidney stones should consume figs with caution.

FODMAP Content

Figs are high in FODMAPs (Fermentable Oligosaccharides, Disaccharides, Monosaccharides, and Polyols), specifically fructans. For individuals with Irritable Bowel Syndrome (IBS) or other digestive sensitivities, consuming high-FODMAP foods can trigger symptoms like bloating, gas, stomach pain, and diarrhea. Those following a low-FODMAP diet should avoid or strictly limit their intake of figs.

High Sugar Content

Although figs are known for their nutritional benefits, they can also have potential drawbacks. Excessive consumption, especially as a remedy for constipation, can sometimes result in digestive discomfort, including diarrhea. Given the high natural sugar content of figs (especially in dried form), individuals with diabetes or those monitoring glycemic intake should account for the carbohydrate load when consuming figs.

Vitamin K and Anticoagulant Drugs

The high vitamin K content in figs poses a concern for individuals taking anticoagulant medications such as warfarin, as vitamin K modulates the activity of such drugs. This interaction is consistent with the established pharmacology of vitamin K and coumarin-type anticoagulants, though specific fig–warfarin interaction studies in humans are not yet published.

Overall Safety Profile

Toxicity studies indicate a large safety margin at therapeutic levels of dosage. There were no significant differences in the levels of blood components in groups consuming fig leaf tea (without furanocoumarin) versus placebo, suggesting it does not cause serious side effects in the range of commonly measured blood constituents with short-term use. However, fig preparations containing furanocoumarins carry meaningful phototoxicity and potential drug-interaction risks.

10. Overall Evidence Assessment

Existing evidence demonstrates a positive impact on the digestive system, lipid metabolism, glucose homeostasis, and cardiovascular protection, and other functions in cancer chemoprevention and maintenance of bone health. Nevertheless, the in vivo and in vitro evidence is significant, but clinical validation is still insufficient because different extraction techniques, different plant parts, phytochemical standardization, and dosage schedules cause variations. Research in animal and human models of health and disease risk provides preliminary health benefit data on figs and their extracts; however, additional well-controlled human studies, particularly using fig fruit, will be required to uncover and verify the potential health benefits.

Among therapeutic applications, the use of fig paste for functional constipation has the strongest and most direct clinical trial evidence. Applications in atopic dermatitis and blood glucose regulation have limited but promising preliminary human trial data. All other pharmacological uses—including anticancer, antimicrobial, antihypertensive, and hepatoprotective effects—remain at the preclinical stage only.
