IngredientesQuassia se refiere a la madera amarga de Quassia amara (nativa de América del Sur y el Caribe) o Picrasma excelsa (de Jamaica y otras regiones del Caribe), ambas miembros de la familia Simaroubaceae. Es conocida por sus compuestos intensamente amargos, especialmente la cuasina y la neocuasina, que le confieren potentes propiedades digestivas, antiparasitarias, antifúngicas e insecticidas.
Tradicionalmente, la quassia se utiliza para estimular la digestión, mejorar el apetito y expulsar parásitos intestinales como los oxiuros y los áscaris. Sus principios amargos estimulan la secreción de enzimas digestivas, lo que la hace útil en el tratamiento de la dispepsia, la digestión lenta y el estreñimiento. La quassia también se utiliza en fórmulas de apoyo hepático y de la vesícula biliar, donde favorece el flujo de bilis y la desintoxicación.
En preparaciones tópicas o como enjuague, el extracto de quassia se utiliza para combatir los piojos y la sarna, y ha sido incluido en remedios herbales para erupciones cutáneas, infecciones fúngicas y afecciones inflamatorias del cuero cabelludo. Generalmente se toma como decocción, tintura o tónico amargo, y a veces se incluye en mezclas vermífugas o amargos digestivos.
Uso Histórico en Medicina:
La quassia tiene una larga historia medicinal en las Indias Occidentales, América del Sur y Europa. Fue introducida por primera vez en la medicina europea en el siglo XVIII tras ser traída de Surinam por un esclavo africano liberado llamado Quassi, quien la utilizaba como un poderoso remedio para las fiebres y los parásitos—de ahí el nombre botánico Quassia amara en su honor.
En el herbalismo europeo, la quassia se convirtió rápidamente en un reconocido tónico amargo y agente antihelmíntico (expulsor de gusanos). Fue incluida en farmacopeas a lo largo de los siglos XVIII y XIX para el tratamiento de gusanos intestinales, congestión hepática, anorexia e indigestión. Su intensa amargura la hacía ideal para estimular las secreciones gástricas y mejorar el flujo de bilis, especialmente en personas con poco apetito o metabolismo lento.
En la medicina ayurvédica y en la medicina tradicional africana, hierbas igualmente amargas con propiedades similares se utilizaban de la misma manera—como tónicos digestivos, febrífugos y depuradores internos—aunque la quassia en sí no es nativa de esos sistemas.

Bioactive peptides derived from casein hydrolysates exhibit antioxidant properties, scavenging free radicals and reducing oxidative stress markers in vitro and in some animal models. Casein hydrolysates produced by high hydrostatic pressure plus proteolytic enzymes show antioxidant and anti-inflammatory activities in cell studies. Human evidence is limited, with most data from in vitro and preclinical systems.
As a high-quality, slowly digested protein, casein contributes to satiety and appetite suppression, though some evidence suggests whey may produce greater acute satiety signaling. Multiple controlled trials and a PMC review found that casein and whey protein produce broadly similar reductions in appetite at matched doses, particularly above a protein threshold of ~25% of energy intake. Casein is recognized as contributing to greater fullness versus carbohydrates.
Casein supplementation supports strength and lean mass gains over long-term resistance training. When total protein intake is matched, casein produces hypertrophy and strength outcomes comparable to whey protein. Presleep casein also accelerates functional recovery in competitive athletes, enabling more consistent performance across training blocks.
Hydrolyzed casein yields bioactive peptides that inhibit angiotensin-converting enzyme (ACE), reducing blood pressure. A 2025 double-blind randomized placebo-controlled trial in 114 prehypertensive/hypertensive adults found that hydrolyzed casein peptides (HCP-C7C12) significantly reduced systolic blood pressure by 9.41% and diastolic blood pressure by 9.53% over 8 weeks. A meta-analysis confirmed that casein-derived lactotripeptides reduce both systolic and diastolic blood pressure across randomized clinical trials.
Casein plays a unique role in calcium transport and absorption via casein phosphopeptides (CPPs), which prevent the formation of insoluble calcium salts and enhance calcium bioavailability in the small intestine. Epidemiological and clinical data link higher dairy protein (including casein) intake to greater bone mineral density. Enzyme-specific casein hydrolysates have been shown to enhance calcium absorption and osteoblast activation.
Casein has been studied against soy protein for effects on plasma lipoprotein profiles. Compared to soy protein, casein is associated with lower lipoprotein(a) concentrations but higher LDL cholesterol, suggesting casein may not be optimal for LDL-lowering versus plant proteins. Meta-analyses of milk protein more broadly show modest improvements in cholesterol with supplementation in metabolic disease populations.
Casein is used as part of protein-based nutritional interventions targeting sarcopenia—the age-related loss of muscle mass and strength. A 2025 systematic review and meta-analysis identified casein alongside whey and plant proteins as key components of multinutritional supplementation strategies for sarcopenia in older adults. Maintaining adequate protein synthesis via casein may help counteract muscle loss associated with aging.
Casein supplementation has been studied for body composition improvement, including fat loss and lean mass preservation during caloric restriction. Its high satiety value and sustained protein release support caloric control and muscle retention. Clinical research supports casein's use in weight management formulations, particularly when combined with exercise.
Casein's slow-release amino acid profile makes it particularly effective for overnight muscle recovery. A systematic review found that ~20–40 g of casein consumed ~30 minutes before sleep improves overnight protein synthetic response in healthy young men following evening resistance exercise. A clinical trial in professional soccer players found presleep casein significantly attenuated muscle soreness and accelerated functional recovery at 12 and 36 hours post-match compared to placebo.
Clinical evidence shows presleep casein supplementation can reduce exercise-induced muscle soreness. In a RCT with professional soccer players, muscle soreness measured by visual analogue scale was significantly lower with casein at 12 hours post-match compared to control. The sustained amino acid delivery of casein is thought to support repair processes during overnight recovery.
Casein, specifically as casein phosphopeptide (CPP) complexed with amorphous calcium phosphate (ACP), is a well-studied biomimetic remineralizing agent. CPP-ACP stabilizes supersaturated calcium and phosphate in plaque, delivering these ions to demineralized enamel. A meta-analysis found clinically significant short-term remineralization effects in in situ trials.
Casein supplementation has been associated with reductions in postprandial triglyceride levels. One study in overweight individuals found casein reduced postprandial triglycerides by 22%. A meta-analysis of 65 RCTs covering milk proteins found improvements in triglycerides with high-quality protein supplementation in adults with metabolic diseases.
