Swertia chirayita
Also known as Chirata
Pronounced Chirata: chih-RAH-tah (Chiretta: chih-RET-tah). Swertia chirayita: SWER-tee-uh chih-RY-ee-tah.
Cold, dry, and intensely bitter: a Himalayan fever-bitter that breaks febrile heat, drains damp-heat from a congested liver, and firms up slack, torpid digestion.
Avoid. There are no adequate human safety data for chirata in pregnancy, and it is traditionally classed among the bitter emmenagogues with a theoretical uterine-stimulant action, so modern references advise against use. On the strength of insufficient data plus the traditional caution, do not use in pregnancy. Sources: Natural Medicines Comprehensive Database (as summarized by RxList and WebMD, Chirata); NCCIH (no monograph; insufficient data); traditional emmenagogue classification in the Ayurvedic and Western bitter-herb literature.
Insufficient data; avoid. There are no reliable data on chirata during lactation and no NIH LactMed monograph, and its intense bitterness may carry into the milk. Prefer a better-documented digestive bitter if one is genuinely needed. Sources: Natural Medicines Comprehensive Database (via RxList and WebMD); NIH LactMed (no entry); NCCIH (insufficient data).
Not established for young children and not traditionally given to them in medicinal doses; the extreme bitterness is poorly tolerated, and its blood-sugar-lowering effect is a concern in small children. If a bitter is genuinely indicated for an older child, use only very low, short-term doses under professional guidance. No formal pediatric safety data exist. Sources: Natural Medicines Comprehensive Database (via RxList and WebMD); NCCIH (insufficient data).
Intensely bitter; large doses can provoke nausea, gastric discomfort, or loose stools, and the sharp bitter may aggravate an active peptic or intestinal ulcer. Because it lowers blood sugar, it can add to the effect of diabetes medicines and cause hypoglycemia, and it should be stopped about two weeks before scheduled surgery. Being cold and drying, it is unsuitable for the cold, deficient, dry, or debilitated constitution, and is best used in short, purposeful courses rather than prolonged self-dosing.
Active peptic or intestinal ulcer and acute gastritis; known hypersensitivity to chirata or other Gentianaceae; the cold, deficient, dry, debilitated constitution and cold spleen and stomach. Use caution in diabetes and in anyone prone to hypoglycemia, and around surgery. Pregnancy and lactation: avoid (see safety fields).
At-risk. Swertia chirayita is assessed as critically endangered under IUCN criteria across its Himalayan range, its wild populations drastically depleted by unregulated overharvesting for national and international trade, worsened because plants are often collected before their seed matures. Do not buy wild-harvested Himalayan material; source only verifiably cultivated or ex-situ-propagated, contaminant-tested herb of confirmed identity, and favor a sustainably grown substitute (for example cultivated gentian or another bitter) where a simple digestive bitter is all that is needed.
Not in canonical biblical texts and unknown to the ancient Mediterranean world of Dioscorides and Pliny. Native to the temperate Himalayas (India, Nepal, and Bhutan), it is a foremost bitter of Ayurveda, Unani, and Siddha medicine (Sanskrit Kirata-tikta, Bhunimba), and entered the British, American, and Indian pharmacopoeias in the colonial period. Grieve records it in A Modern Herbal (1931) as Chiretta.
