Synopsis

Pluchea: A Comprehensive Encyclopedic Reference

1. Identity: Botanical Classification, Common Names, and Natural Distribution

Taxonomy and Nomenclature

Pluchea is a genus of flowering plants in the tribe Inuleae within the family Asteraceae. Members of this genus are commonly known as camphorweeds, plucheas, or, less uniquely, fleabanes. The genus comprises approximately 80 species.

The most extensively researched and medicinally prominent species is Pluchea indica (L.) Less. Its recognized botanical synonyms include Baccharis indica L. and Erigeron denticulatum Burm. f. Common English names include Indian camphorweed, Indian fleabane, and Indian pluchea. Other medicinally noted species in the genus include Pluchea lanceolata, used in India and Afghanistan, and Pluchea odorata (sweetscent, saltmarsh fleabane), which ranges from Ontario to Bolivia.

Regional Common Names

P. indica is known by many regional names: Khlu (Thai), Kukrakonda, Kakronda, or Munjhu rukha (Bengali), Kuo bao ju (Chinese), luntas (Javanese), Beluntas (Malaysia, Indonesia, Bahasa), and kalapini (Philippines). In Indonesia alone, regional names include Bluntas (Bali), Baruntas (Sunda), Luntas (Java), Baluntas (Madura), Lamutasa (Makassar), and Lenabou (Timor). Internationally it is also referred to as Luan Yi in China and Phatpai in Vietnam.

Botanical Description and Habitat

Pluchea indica is a slender, erect, much-branched, evergreen shrub, growing 1–3 metres tall. Main botanical characters for identification are a bushy shrub life-form, with leaves that are short-stalked, obovate, thick papery, with a tapering base and serrated margin. Crushed leaves are very aromatic.

P. indica is an evergreen shrub found abundantly in salt marshes and mangrove swamps, attaining 1 to 2 m in height, and plays an important role in maintaining the ecological balance in coastal areas. It mainly distributes in the tropical and subtropical regions of Africa, Asia, America, Australia, and China's southern provinces. The coastal species occurs in open sites at the landward side of mangroves.

Common Preparations and Dosage Forms

Its traditional uses take the form of both medicine and food. Traditionally, P. indica leaves are prepared as herbal beverages by boiling or steeping fresh leaves. Dried leaves and leaf extracts have also been commercially available as herbal tea, owing to known blood glucose-lowering properties. According to available data, P. indica can be prepared as an extra supplement eaten daily in the form of herbal tea or capsules.

In research settings, preparations have included aqueous (water) extracts, ethanolic (70% or 95% ethanol) extracts, methanolic extracts, hexane fractions, chloroform fractions, and essential oils obtained by hydrodistillation. Nanoparticle (NP) formulations of leaf extract have also been investigated for pharmaceutical applications.

2. Traditional and Historical Uses

Southeast Asia: Indonesia, Malaysia, Thailand

The use of P. indica as a traditional medicinal preparation varies across different regions of Indonesia and has been empirically validated in each area. Empirically, Beluntas is often used in traditional medicine to eliminate body and breath odor, enhance appetite, address digestive disorders, relieve pain from rheumatism, bone pain, and lower back pain, reduce fever, and manage irregular menstruation and leukorrhea.

Traditional medicine in Bali, referred to as "Usadha," incorporates P. indica leaves, which are processed into traditional beverages known as "Loloh," prepared using spices and plants.

In Thailand, the fresh leaves of P. indica are used as the main ingredient in many local dishes. P. indica tea (PIT) is widely consumed as a health-promoting drink in Southeast Asia.

India and the Ayurvedic Tradition

P. indica (Asteraceae), commonly known as Indian camphorweed, pluchea, or marsh fleabane, has gained great importance in various traditional medicines for its nutritional and medicinal benefits. In Patna, the leaves and roots are utilized as an astringent and antipyretic. The plant holds a place in Ayurvedic practice particularly for its aromatic camphor-like properties.

China

As a folk medicine in Guangxi (China), it exhibits the function of softening hardness and dissolving lumps. As a food, it possesses the activity of warming the stomach. It is recognized as a medicine and food dual-use plant in China.

Scope of Traditional Indications

Traditionally, the plant is utilized to cure several illnesses, including lumbago, kidney stones, leucorrhea, inflammation, gangrenous and atonic ulcer, hemorrhoids, dysentery, eye diseases, itchy skin, acid stomach, dysuria, abdominal pain, scabies, fever, sore muscles, diabetes, and rheumatism. The plant or its leaves in the form of tea are commonly used for treating diabetes and rheumatism. A popular herbal remedy within its native range, the plant is gathered from the wild and also traded locally, especially for its use as a diuretic.

The traditional practices and knowledge on P. indica utilization rely exclusively on observations and practical experience that are passed on verbally from one generation to the next, with little formally documented evidence.

3. Key Constituents and Active Compounds

Primary Phytochemical Classes

Various biomolecules have been isolated from P. indica, including thiophenes, terpenes, quinic acids, sterols, lignans, phenolics, and flavonoids. Its main constituents are quinic acids, flavonoids, thiophenes, phenolic acids, as well as sesquiterpenes.

Caffeoylquinic acids and terpene glycosides are the main bioactive compounds from the aerial parts and leaves of P. indica, respectively.

Thiophenes

Four new thiophenes — (3′′R)-pluthiophenol, (3′′R)-pluthiophenol-4′′-acetate, 3′′-ethoxy-(3′′S)-pluthiophenol, and 3′′-ethoxy-(3′′S)-pluthiophenol-4′′-acetate — together with twenty-five known compounds, were obtained from the 70% ethanol-water extract of the aerial parts of P. indica. A particularly significant isolated thiophene is PITC-2: PITC-2 was isolated from the methanolic root extract of tissue-cultured P. indica. PITC-2 is a thiophene derivative, specifically 2-(Prop-1-ynyl)-5(5,6-dihydroxyhexa-1,3-diynyl)-thiophene.

Flavonoids and Phenolic Acids

The major phytoconstituents detected in the leaf ethanol extract (PILE) by LC-MS include phenolic acids (3,4-dicaffeoyl-1,5-quinolactone, apigenin 7-(2′′,3′′-diacetylglucoside), and campesteryl ferulate) and flavonoids (quercetin, 6-hydroxykaempferol 7-glucoside, 8-hydroxy-luteolin 8-glucoside, and trans-trismethoxy resveratrol-d4).

Chemical analysis of P. indica tea demonstrated that it contains total phenolic content (TPC), total flavonoid content (TFC), 4-O-caffeoylquinic acid (4-CQ), 5-O-caffeoylquinic acid (5-CQ), 3,4-O-dicaffeoylquinic acid (3,4-CQ), 3,5-O-dicaffeoylquinic acid (3,5-CQ), 4,5-O-dicaffeoylquinic acid (4,5-CQ), beta-caryophyllene, and gamma-gurjunene, which may play important roles in inhibiting hyperlipidemia and hyperglycemia.

Essential Oil Constituents

By hydrodistillation and GC-FID/MS analysis, essential oils from fresh leaves and stem barks were dominated by sesquiterpene hydrocarbons (76.8–82.2%) and their oxygenated derivatives (8.4–19.0%); β-selinene (42.0–43.5%) and silphinene (21.1–22.9%) were the main compounds.

Nutritional Constituents

The plant is a rich source of calcium, vitamin C, dietary fiber, and β-carotene. Alkaloids, tannins, and saponins have also been detected in crude aqueous extracts of leaves and roots.

4. Established Mechanisms of Action

Anti-inflammatory Mechanisms

P. indica root and leaf extracts revealed anti-inflammatory potential towards different types of induced inflammations using various models. The suppression of NF-κB, attenuation of antioxidant enzymes, up-regulation of HO-1, and inhibition of PGE2 and 5-LOX are the reported molecular mechanisms.

Earlier mechanistic work established the involvement of the lipoxygenase pathway: studies were carried out to evaluate the influence of the methanol fraction of P. indica root extract (PIRE) on both in vivo and in vitro free radical-scavenging activities, CCl4-induced lipid peroxidation, and the metabolism of arachidonic acid by lipoxygenase. PIRE produced significant anti-inflammatory activity against glucose oxidase-induced paw edema in vivo, and inhibited hydroxyl radical and superoxide generation, lysis of erythrocytes induced by hydrogen peroxide, CCl4-induced lipid peroxidation, and dioxygenase activity of lipoxygenase.

Antioxidant Mechanisms

The methanol fraction of P. indica root extract was found to possess antioxidant activity. High contents of phenolic acids and flavonoids in the plant are well-known for their antioxidant and anti-inflammatory activities. In vitro comparisons have been notable: antioxidant properties of P. indica leaves have been reported to be stronger than those of Curcuma longa (turmeric) rhizomes, and P. indica tea has also been reported to have stronger antioxidant properties than green tea of Camellia sinensis.

Antidiabetic Mechanisms

The presence of quercetin and trans-trismethoxy resveratrol-d4 (a resveratrol derivative) is presumed to significantly contribute to the hypoglycemic activity of the leaf ethanol extract (PILE). PILE pretreatment effectively ameliorated cytokine-induced β-cell injury in streptozotocin (STZ) mice; the possible antidiabetic mechanism was elucidated as PILE protecting β-cells by inhibiting apoptosis and enhancing cell proliferation. Computational investigations have identified active compounds in P. indica with potential to treat diabetes by targeting PPARG (peroxisome proliferator-activated receptor gamma).

Anticancer Mechanisms

Treatment with crude aqueous extracts of P. indica leaf and root for 48 hours resulted in a significant 75% and 70% inhibition on proliferation and viability of GBM8401 (glioma) and HeLa (cervical) cancer cells, respectively. Root extract inhibited focus formation and promoted apoptosis of HeLa cells. Phosphorylated-p53 and p21 were induced in cells treated with crude aqueous extracts of P. indica root.

In human nasopharyngeal carcinoma (NPC) cells, root ethanolic extract significantly increased cells in sub-G1 phase and the extent of DNA fragmentation in a dose-dependent manner. The apoptotic process involved up-regulation of pro-apoptotic Bax protein and down-regulation of anti-apoptotic Bcl-2 protein, increasing Bax/Bcl-2 ratios. The p53 protein was up-regulated in a concentration-dependent manner, indicating that the extract induces the apoptosis-signaling pathway in NPC cells by activation of p53 and regulation of apoptosis-related proteins.

Antimicrobial Mechanisms

Leaves and roots of P. indica, including tea leaves, inhibit the growth of Gram-positive and Gram-negative bacteria. Compounds isolated from P. indica — including novel thiophenes and known isolates — displayed significant inhibitory activities on LPS-induced nitric oxide (NO) production at 40 µM in RAW 264.7 macrophages, while other compounds possessed moderate inhibitory effects.

5. Scientific Evidence by Area of Use

5.1 Metabolic Health: Blood Glucose and Lipid Profile

Human Clinical Evidence (Randomized Controlled Trial):

A study aimed to investigate whether P. indica tea has antidyslipidemic and antihyperglycemic effects and toxicity in humans, designed as a randomized clinical trial with forty-five participants with prediabetes. Participants were randomized to receive placebo tea, 1.5 g of P. indica tea (PIT), and 1.5 g Camellia sinensis tea (green tea) once daily for 12 weeks. Outcome measurements included the oral glucose tolerance test (OGTT), total cholesterol, triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), blood urea nitrogen (BUN), creatinine, ALT, alkaline phosphatase (ALP), and complete blood count (CBC) before and after treatment. This randomized clinical trial revealed that the tea alleviated dyslipidemia and hyperglycemia, where it noticeably lowered TG and LDL-C and raised HDL-C.

Evidence Strength: This constitutes the only published randomized clinical trial in humans identified in the literature. The sample size of 45 participants is small, limiting generalizability. The study was conducted at a single site in Nakhonratchasima, Thailand. This evidence is therefore preliminary in the clinical domain.

Animal Studies:

Mice were pre-treated with PILE at 50 mg/kg (PILE 50) or 100 mg/kg (PILE 100) for 2 weeks before streptozotocin (STZ) stimulation, and the treatment continued for 4 or 8 weeks. Results revealed that PILE 100 mice exhibited improved blood biochemistry, maintained a higher body weight, had decreased hyperglycemia, and restored islet architectures compared to non-treated STZ mice.

In a separate animal study, PILE alleviated hyperglycemia-induced liver injury by normalizing various mediators of oxidative stress, inflammation, and apoptosis. In this model, mice were first pretreated with PILE at either 50 mg/kg (PILE 50) or 100 mg/kg (PILE 100) two weeks prior to the induction of hyperglycemia by multiple low doses of STZ.

Evidence Strength for animal diabetes research: Multiple independent in vivo rodent studies consistently support antihyperglycemic and antidyslipidemic effects. These are preclinical findings and cannot be directly extrapolated to humans without further trials.

5.2 Anti-inflammatory Activity

Preclinical (In Vivo and In Vitro) Evidence:

P. indica was assessed for anti-inflammatory activity using various models. The plant showed promising potential, which supported the pharmacological basis of its uses as a traditional herbal medicine for treating inflammation. Documented molecular mechanisms include NF-κB suppression, HO-1 upregulation, and 5-LOX and PGE2 inhibition.

The stem bark essential oil strongly monitored the growth of four cancer cell lines (K562, HeLa, HepG2, and MCF-7) with IC50 values of 2.89–7.34 μg/mL. Both leaf and stem bark essential oil samples showed strong anti-inflammatory activity against NO production with IC50 values of 21.81–23.18 μg/mL.

Evidence Strength: All current anti-inflammatory evidence is preclinical — in vitro cell-culture and animal model studies. No human clinical trials specifically examining anti-inflammatory endpoints for P. indica have been published to date.

5.3 Antioxidant Activity

Preclinical Evidence:

Antioxidant properties of P. indica leaves have been reported to be stronger than those of Curcuma longa (turmeric) rhizomes, and P. indica tea has been reported to have stronger antioxidant properties than green tea of Camellia sinensis. These comparative antioxidant findings are based on in vitro assays (e.g., DPPH radical scavenging), and their clinical relevance in humans remains untested.

Evidence Strength: In vitro antioxidant evidence is strong and consistent; however, in vitro antioxidant assays do not reliably predict in vivo efficacy or human clinical benefit. Evidence remains at the preclinical level.

5.4 Anticancer Activity

In Vitro and In Vivo Preclinical Evidence:

A study evaluated the anti-cancer activity of P. indica tea leaves by measuring cytotoxicity on breast and cervical cancer cells. Two extracts were prepared using hot water (PA) and ethanol (PE). MTT and clonogenic assays were applied to determine the cytotoxic effect on cancer cells from human breast (MDA-MB-231 and MCF7) and cervix (SiHa, HeLa, and C-33A) and non-cancer Vero cells. Significant reduction in cell viability and proliferation capability was observed in all cancer cells; PE was more effective. Lower toxicity was detected in Vero (non-cancer) cells, indicating selectivity. The intracellular ROS level was augmented in treated cancer cells, inversely correlated to cell viability, suggesting cancer toxicity was likely induced by intracellular oxidative stress. Flavonoids were found abundantly in the extracts and flavonoid content was most related to the cytotoxic activity (r = 0.815).

For the thiophene compound PITC-2: the main objective was to evaluate the in vivo antitumor activity of PITC-2 against sarcoma-180 cancer cells in Swiss albino mice. The antitumor activity was evaluated by treatment with PITC-2 at doses of 2.5 and 5 mg/kg b.w. for 21 days on the sarcoma-180 mice model. Cell viability was studied using MTT assay, and cell apoptosis, G1 cell cycle arrest, and reduction in tumor cell proliferation were evaluated by histopathological analysis and protein expression through immunohistochemistry.

The root hexane fraction exhibited a potent suppressive potential versus GBM (glioblastoma) cell growth, apparently by inducing G0/G1-phase cell cycle arrest, and enhanced autophagy by increasing the formation of acidic vesicular organelles (AVOs), LC3-II expression, and p38 and JNK phosphorylation.

Evidence Strength: All anticancer evidence for P. indica is strictly preclinical — in vitro cell-line studies and rodent tumor models. The in vitro anti-cancer effects of crude aqueous extracts of P. indica leaf and root indicate that it has sufficient potential to warrant further examination and development as a new anti-cancer agent. No human clinical trials for oncological applications have been conducted.

5.5 Anti-infective (Antimicrobial, Antifungal, Antiparasitic) Activity

P. indica is popularly consumed as a medicinal vegetable and used in ethnomedicine to treat various diseases including gastrointestinal problems such as dysentery and leucorrhea, which are due to bacterial, fungal, or parasitic infections. There have been numerous studies on the antimicrobial effects of the plant due to these ethnomedicine uses.

Literature searches across Scopus, ScienceDirect, PubMed, Google Scholar, Wiley Online Library, and ACS Publications identified 35 documents studying the anti-infective activity of P. indica. Leaves and roots of P. indica, including tea leaves, inhibit the growth of Gram-positive and Gram-negative bacteria and possess anti-inflammatory properties.

Evidence Strength: Anti-infective evidence is confined to in vitro microbiological studies and some animal models. No human clinical trials on infectious disease endpoints have been published for P. indica. The body of preclinical evidence is, however, substantial in volume.

5.6 Wound Healing and Oral Mucosal Applications

One study investigated the effect of P. indica leaf ethanol extract and its nanoparticles (NPs) on cytotoxicity, cell survival, and migration of a human oral squamous carcinoma cell line (HO-1-N-1). Cell viability was measured using the MTT assay to assess the effect of extract and NPs (1–500 μg/mL) on cytotoxicity and cell survival. Nanoparticles increased cytotoxicity of the extract, increased the migration of cells at low concentration, and increased colloidal stability of the extract in an oral spray formulation. This work is relevant to potential wound-healing applications in oral mucosal tissue, though it remains at the in vitro stage.

5.7 Neuropharmacological Activity

Neuropharmacological actions of P. indica root extract have been investigated in socially isolated mice (referenced as Thongpraditchote et al., 1996, published in Biological and Pharmaceutical Bulletin), suggesting central nervous system activity, but this research is decades old and has not been followed by human trials. Methanolic extract of leaves, as well as hexane extract of both leaves and stems, were detected to have acetylcholinesterase inhibitory properties.

7. Dosages Reported in Studies

The following dosages are reported strictly as stated in peer-reviewed sources:

In the human randomized clinical trial in prediabetic participants, the intervention dose was 1.5 g of P. indica tea once daily for 12 weeks.
In murine STZ-induced diabetic models, mice were pre-treated with PILE at 50 mg/kg (PILE 50) or 100 mg/kg (PILE 100) for 2 weeks before streptozotocin stimulation, with treatment continuing for 4 or 8 weeks.
In the hepatoprotective study, mice were pretreated with PILE at either 50 mg/kg (PILE 50) or 100 mg/kg (PILE 100) 2 weeks prior to hyperglycemia induction by STZ.
In the in vivo antitumor study with PITC-2, the antitumor activity was evaluated by treatment at doses of 2.5 and 5 mg/kg body weight for 21 days on the sarcoma-180 mice model.
A P. indica-based health supplement was described as potentially usable as an antihyperglycemic and antidyslipidemic treatment with low toxicity up to a dose of 600 mg/kg/day (in mice).
In the oral mucosal wound-healing study, extract and nanoparticle concentrations of 1–500 μg/mL were used in cell viability assays.

No standardized human dosage recommendation for P. indica as a dietary supplement has been established by any regulatory body at this time.

8. Safety Considerations

Acute Toxicity (Animal Studies)

Acute toxicity assessment was carried out using different doses. One study proved that the methanol extract of the leaves did not display any sign of toxicity in rats at a dose of 3200 mg/kg orally.

Subchronic / Repeated-Dose Toxicity

In one study, P. indica tea at a dose of 600 mg/kg/day was found to be non-toxic to the kidney, liver, and blood in mice.

In the murine diabetic model study, blood biochemical analysis of markers related to kidney and liver function was performed to validate whether administration of PILE could produce toxicity. No significant variance in serum TG, TC, BUN, creatinine, albumin, AST, ALT, and ALP was observed among all experimental groups before STZ stimulation, indicating the safety of PILE administration.

Human Toxicity Assessment

Toxicity assessment of P. indica tea in randomized clinical trials on prediabetic humans revealed no toxicity to the liver, kidney, and blood, as evident by the lack of any remarkable variation in ALT, BUN, creatinine, CBC, and ALP of the P. indica-received group compared to the placebo.

Conclusions from the randomized clinical trial state that P. indica tea may ameliorate hyperglycemia and dyslipidemia in prediabetes people, that it may not be toxic to the kidney, liver, and blood, and that it has the potential to develop into a health-promoting tea or herbal medicine for hyperglycemia and dyslipidemia prevention.

Gaps in Safety Data and Research Needs

Further studies on drug interactions, mechanism of action, pharmacokinetics, toxicology, and metabolism, as well as clinical trials, should be carried out. The single published human RCT (n=45, 12 weeks) does not provide sufficient evidence to characterize the long-term safety profile in diverse populations. Further studies on drug interactions, mechanism of action, pharmacokinetics, toxicology, and metabolism, as well as clinical trials, are needed.

Key documented gaps include: absence of pharmacokinetic data in humans; absence of drug-interaction studies; no safety data in pregnant or lactating women; no pediatric safety data; and no long-term (beyond 12 weeks) human safety data.
