Chebulic Myrobalan
Also known as: Terminalia chebula, Chebulic Myrobalan, Haritaki, Black Myrobalan, Ink Tree
Overview
Terminalia chebula, commonly known as Chebulic Myrobalan or Haritaki, is a deciduous tree native to tropical regions of South East Asia. Its fruit is widely used in traditional Ayurvedic, Unani, and Siddha medicine due to its rich phytochemical composition, including polyphenols, flavonoids, terpenes, anthocyanins, and glycosides. Traditionally, it has been used to treat ailments such as chronic diarrhea, gastroenteritis, constipation, asthma, ulcers, hemorrhoids, cold, and cough. The fruit contains bioactive compounds like chebulic acid, chebulinic acid, and chebulaginic acid, which contribute to its pharmacological activities. While extensive research has explored its effects, more advanced clinical trials are needed to confirm its efficacy and safety. Available evidence, primarily from laboratory studies, traditional use, and limited clinical trials, suggests a broad spectrum of biological activities, warranting further investigation.
Benefits
Terminalia chebula offers several evidence-based benefits. Its extracts exhibit significant antioxidant and anti-inflammatory properties, potentially preventing tissue damage and mitigating various diseases. Bioactive compounds contribute to anti-diabetic and cardioprotective activities, aiding glucose and lipid metabolism and preventing atherogenesis and endothelial dysfunction. Chebulinic acid demonstrates bacteriostatic effects against Helicobacter pylori (HP), inhibiting bacterial growth. Traditionally, it supports digestive health, addressing chronic diarrhea, gastroenteritis, and constipation. Emerging research suggests anti-cancerous and anti-arthritic properties, though further studies are needed. A study on COVID-19 patients showed that a combination including T. chebula reduced hospitalization days and decreased ICU admissions and deaths. These benefits make it potentially valuable for individuals with diabetes, cardiovascular diseases, and gastrointestinal issues.
How it works
Terminalia chebula operates through multiple biological pathways, including antioxidant, anti-inflammatory, antimicrobial, and anti-diabetic mechanisms. Its bioactive compounds neutralize free radicals, inhibit bacterial growth, and modulate metabolic pathways. It interacts with the digestive system by aiding digestion and treating gastrointestinal issues. In the cardiovascular system, it prevents atherogenesis and endothelial dysfunction. It influences the immune system through its anti-inflammatory and antimicrobial activities. Key molecular targets include chebulic acid, chebulinic acid, and chebulaginic acid, which exhibit antioxidant, anti-inflammatory, and antimicrobial properties. The bioavailability of T. chebula compounds varies depending on the extraction method and solvent used, affecting absorption.
Side effects
Terminalia chebula is generally considered safe when used in traditional doses, but comprehensive clinical data on long-term safety is limited. Common side effects are not well-documented, but traditional use suggests it is generally well-tolerated. Gastrointestinal upset is a potential side effect, although not commonly reported. No specific uncommon or rare side effects have been documented in available literature. Potential interactions with diabetes medications and cardiovascular drugs may occur due to its anti-diabetic and cardioprotective effects, requiring further investigation. Caution is advised for pregnant or breastfeeding women due to limited safety data. Children and elderly individuals should use it under medical supervision. Monitoring is recommended due to the lack of comprehensive clinical trials.
Dosage
The minimum effective dose of Terminalia chebula varies depending on the specific use and extraction method. Traditional use involves consuming the fruit or its extracts in various forms, but the optimal dosage range is not well-defined and requires further clinical studies. There is no established maximum safe dose, but traditional use suggests that moderate consumption is safe. Timing can vary depending on the specific health condition being treated; for digestive issues, it may be taken after meals. It is available in various forms such as capsules, powders, and decoctions, which may influence bioavailability and absorption. Absorption can be influenced by the extraction method and solvent used. No specific cofactors are required, but consuming it with other herbs or nutrients may enhance its bioavailability.
