Terminalia chebula contains tannins, particularly chebulic acid, which provide potent antioxidant effects through free radical scavenging mechanisms. This Ayurvedic herb supports digestive health, cardiovascular function, and liver detoxification through its gallic acid derivatives.
Reported Benefits (Provisional)
Origin & History
Terminalia chebula, known as Halela, is a tree native to South Asia. Its fruit is used in traditional medicine for various health benefits.
Research Narrative (Provisional)
Research indicates that Terminalia chebula may have antioxidant and anti-inflammatory properties. Some studies have shown its potential in supporting digestive health.
Preparation & Dosage
Dosage guidance is withheld because the publication gate has not recorded adequate support for this profile.
Nutritional Profile
Terminalia chebula (Halela/Haritaki) is valued primarily for its bioactive phytochemical profile rather than macronutrient content. Per 100 g of dried fruit: Dietary fiber: 20–30 g (predominantly soluble fiber including mucilage and pectin); Protein: 4–6 g; Carbohydrates: 50–60 g; Fat: 3–5 g; Moisture: 8–12 g. Key bioactive compounds include: Tannins (hydrolyzable) — 30–45% of dry weight, primarily chebulic acid (2–4%), chebulagic acid (3–6%), chebulinic acid (1.5–3%), gallic acid (1–2.5%), and ellagic acid (0.5–1.5%); Triterpenoids — arjunolic acid, arjungenin, and chebulosides I & II (collectively ~0.5–1.5%); Flavonoids — including quercetin, kaempferol, and luteolin (trace to ~0.2%); Vitamin C: 200–500 mg per 100 g (varies widely by preparation and source); B-vitamins (B1, B2, B3) in trace amounts; Minerals: potassium (400–600 mg/100 g), calcium (50–100 mg/100 g), magnesium (40–80 mg/100 g), iron (3–8 mg/100 g), zinc (1–3 mg/100 g), selenium (trace, ~5–15 µg/100 g), copper (~0.5–1.5 mg/100 g), manganese (~1–3 mg/100 g); Phenolic acids: including ferulic acid, vanillic acid, and p-coumaric acid (collectively ~0.5–1%); Anthraquinones: sennoside-like compounds in trace quantities contributing to laxative properties. Bioavailability notes: Gallic acid and ellagic acid have moderate oral bioavailability (~20–30%), though ellagic acid is extensively metabolized by gut microbiota into urolithins, which may have enhanced systemic bioactivity. Chebulic acid and chebulagic acid show relatively higher water solubility than many polyphenols, improving absorption when consumed as aqueous decoctions (a traditional Middle Eastern preparation method). Tannin-rich extracts may inhibit iron and protein absorption if consumed alongside meals, so traditional use typically recommends consumption on an empty stomach or between meals. Vitamin C bioavailability is high (~70–90%) but degrades significantly with heat processing. The triterpenoid fraction has low oral bioavailability (~5–10%) but may be enhanced when taken with dietary fats.
Reported Mechanism (Provisional)
Terminalia chebula's primary bioactive compounds, chebulic acid and ellagic acid, inhibit lipid peroxidation and scavenge reactive oxygen species. These tannins modulate digestive enzymes and enhance bile acid production, promoting gastrointestinal motility. The herb also inhibits HMG-CoA reductase, contributing to cholesterol-lowering effects.
Clinical Narrative (Provisional)
Human studies with 500-1000mg daily doses show 10-15% cholesterol reduction over 12 weeks in small trials of 40-60 participants. Animal studies demonstrate hepatoprotective effects and improved digestive function, but large-scale human clinical trials are limited. Most evidence comes from traditional use and preclinical research rather than robust randomized controlled trials.
