Woodfordia fruticosa
Also known as fire flame bush, shiranjitea, woodfordia, dhawai, Dhataki, Dhatupushpi, Agnijvala.
Woodfordia fruticosa is a straggling shrub of the loosestrife family with long arching branches that flame with clusters of small scarlet tubular flowers in the dry season, growing on hillsides, rocky slopes and forest edges throughout India from the Himalayan foothills to the Deccan and across Southeast Asia and East Africa. Ayurveda calls it Dhataki and uses the dried flower as a cooling astringent for diarrhea, dysentery, bleeding and wounds, but its most distinctive role is as the fermentation starter of the classical medicinal wines, the arishtas and asavas, where its yeasts and tannins set and steady the ferment. It is one of the most heavily traded flowers in the Indian herbal industry for that reason.

Prabhava: sandhana (fermentation starter): the flowers initiate and regulate the fermentation of the classical arishta and asava wines. Karma: stambhana (checks discharge, astringent); raktastambhana (hemostatic); grahi (binds loose stool); vranaropana (heals wounds); garbhasthapana (stabilizes pregnancy, traditional); krimighna (anthelmintic); kushthaghna (cures skin disease); trishnanigrahana (relieves thirst); sandhaniya (promotes union of wounds and fractures); madakari (mildly intoxicating in old texts, via fermentation); pittahara (pacifies pitta).

The dried flowers are the drug, given as churna with honey or rice water for diarrhea and bleeding, as kwatha, and dusted or applied as a paste to wounds, ulcers and burns; above all they are added to the sweetened decoctions and juices of the arishta and asava class to start and regulate fermentation, which is why the flower is present in dozens of classical wines.

Overview. Woodfordia fruticosa is a straggling shrub of the loosestrife family with long arching branches that flame with clusters of small scarlet tubular flowers in the dry season, growing on hillsides, rocky slopes and forest edges throughout India from the Himalayan foothills to the Deccan and across Southeast Asia and East Africa.

It is one of the most heavily traded flowers in the Indian herbal industry for that reason.
Clinical Notes. Dhataki is the flower an Ayurvedic physician reaches for when a cooling, drying astringent is needed: pitta diarrhea and dysentery with blood and thirst, heavy bleeding from the uterus or rectum, leukorrhea and weeping ulcers.
Ayurvedic Profile. Rasa: kashaya (astringent), katu (pungent, slight). Virya: sheeta (cooling). Vipaka: katu (pungent). Guna: laghu (light), ruksha (dry). Dosha: pacifies kapha and pitta; may aggravate vata in excess. Prabhava: sandhana (fermentation starter): the flowers initiate and regulate the fermentation of the classical arishta and asava wines.
Conservation. Wild flowers are harvested in very large quantities for the arishta industry and heavy or destructive collection has depleted some populations; encourage cultivation and sustainable harvest.
Dhataki stands in 38 documented formulas in the library, among them Abhayāriṣta, Aravindāsava, Aśokāriṣta, Aśvagandhādyariṣṭa, Uśīrāsava, Kanakāsava.
