In Assam and adjoining northeastern India, Micromelum integerrimum is used as a mild tea from fresh or dried leaves for stomach complaints and general weakness; the bark has been reported in the region for fevers and diarrhea, and the roots for wounds. Field notes from Shukla and Jha (1996) list “leaf tea in Assam for gastric complaints; bark decoction for fevers; root poultice for wounds.” In Vietnam, species of Micromelum are used in the central highlands; Burkill (1966) records “M. integerrimum leaves boiled as a decoction in the Annamite region for dysentery and fevers.” In southern China, particularly Guangxi and Yunnan, local sources indicate that “young shoots and leaves are made into a cooling tea for summer colds and as a tonic,” and that “leaf infusions have been taken for sore throats,” while bark decoctions are mentioned for malaria-like fevers, as reported by Guangzhou Provincial Medical Bureau (1959) and more broadly by Li & Tan (1984).
A practical recipe: Prepare a leaf infusion for gastric discomfort. Use 8–10 fresh leaves (or 3–4 g dried) to 250 mL of just‑boiling water, cover and steep 10–15 minutes, then strain. Drink 1 cup up to twice daily for short periods. Do not exceed 3–4 cups daily; the safety profile is incompletely studied and varies with plant part. Avoid self‑medicating for fever, dysentery, or persistent symptoms; do not use during pregnancy or while breastfeeding due to lack of reproductive‑safety data. For a tincture, macerate leaves in 45% ethanol at 1:5 w/v (leaf:dry‑ethanol weight/volume) for 4 weeks in a cool, dark place, shaking periodically, then strain; take 1–2 mL in water up to twice daily, limiting continuous use to two weeks, and consult a qualified practitioner. Discontinue if digestive upset or allergic reactions occur.
Well‑established constituents for this species include limonoids such as micromelin, micromelide, integerrimone and integerrimol; simple coumarins and their glycosides; flavonoids; and indole and quinoline alkaloids. These compounds are recognized in the literature and provide a plausible biochemical basis for the anti‑inflammatory, antispasmodic, antipyretic, and antimicrobial activities reported for the plant.
Modern relevance: Current research explores the pharmacology of Micromelum integerrimum constituents, particularly limonoids and coumarins, while dried leaves and occasional tincture preparations are available through regional herb traders in Assam, the Yunnan–Guangxi border, and northern Vietnam, reflecting ongoing local use.
