''Woodfordia fruticosa (L.) Kurz''), popularly known as '''Dhataki''' (Fire flame bush), is a deciduous, much-branched shrub of the family Lythraceae. Its red flowers are widely used in [[Ayurveda]] as an astringent, as a wound-healing drug and as a fermenting agent in ''Arishtas'' and ''Asavas''. Most modern research is published under the name ''Woodfordia fruticosa''. | ||

==Traditional Context== | |||
In Ayurvedic therapeutics Dhataki is included among the ''Sandhaniya'' (promoting union of tissues) and ''Purishasangrahaniya'' (faecal astringent) groups. It has cold potency (''sheeta veerya'') and pungent post-digestion effect (''katu vipaka''), and pacifies Pitta and Kapha doshas. | |||

Woodfordia fruticosa has yielded the following major classes of compounds, mainly from the flowers and leaves:<ref name="Das2007" /> | |||

== Pharmacological Activities | ==Pharmacological Activities and Therapeutic Efficacy== | ||
All studies below are preclinical (animal or in vitro). No controlled human clinical trial is cited in this monograph. Most studies used extracts of a specific plant part, which is stated for each topic. | |||
=== | ===Antidiarrhoeal activity (Atisara)=== | ||
Methanolic extracts of the bark (200 and 400 mg/kg) and of the leaf (400 mg/kg) showed statistically significant antidiarrhoeal activity in rodents. This study used leaf and bark, not the flower, which is the part used in Ayurveda.<ref name="Rahman2023" /> | |||
=== | ===Wound healing (Vrana)=== | ||
The ethanolic extract of the flowers (250 and 500 mg/kg in rats) showed dose-dependent wound-healing activity in excision, incision and dead-space models, with increased wound contraction and breaking strength. The ethanolic extract also showed strong, broad-spectrum antimicrobial activity.<ref name="Verma2013" /> | |||
== | ===Anti-inflammatory activity=== | ||
Methanol, ethyl acetate and hydro-alcohol extracts of the flowers (200 mg/kg, oral) inhibited egg-albumin and carrageenan-induced inflammation in rats. The extracts also showed antioxidant (free-radical stabilizing) and mast-cell stabilizing activity, and in vitro membrane stabilization.<ref name="Ghante2014" /> | |||
== Summary of Therapeutic Profile == | ==Safety, Toxicity and Dosage== | ||
* '''Toxicity:''' The ethanolic flower extract produced no toxicity symptoms or mortality up to 2000 mg/kg, orally, in rats in an acute toxicity study following OECD guidelines.<ref name="Ghante2012" /> | |||
* '''Precautions (Ayurvedic, no experimental reference cited):''' Because of its strong astringent (''kashaya'') nature, people with chronic severe constipation should use it cautiously. No reference could be verified for the pregnancy-related safety of Dhataki, so no statement is made here; use only under physician supervision. | |||
* '''Standard therapeutic dose:''' Flower powder (churna) 3–6 g daily, or as advised by an Ayurvedic physician (see Dose above). | |||
