02 Constituent chemistry

Chemical classMarker compoundSynthetic analogue in use
Phenolic lipids Bhilawanol
Fruit
No synthetic analogue. Bhilawanol is a urushiol-type alkyl catechol, chemically analogous to the poison-ivy allergen.

The analogue column is what makes the interaction reasoning tractable: where a constituent has a marketed structural counterpart, the counterpart's interaction profile is the starting hypothesis for the plant.

03 Stated application

Reported activity
Ayurvedic use (Bhallataka) in refractory arthritis and chronic skin disease, ONLY after shodhana (repeated boiling in water then milk). Classified as Upavisha in Ayurvedic texts and listed as a poisonous plant under the Indian Drugs and Cosmetics Act 1940.
Reported adverse effects
Irritant and allergic contact dermatitis, often severe and blistering. Presents in many patterns (vesiculobullous, erythema-multiforme-like, zoster-like) and is FREQUENTLY MISDIAGNOSED as fixed drug eruption or erythema multiforme. Ectopic spread via hands to face and genitalia; airborne and mail-borne cases reported. Used deliberately to produce factitious dermatitis (dermatitis artefacta) - consider in unexplained recurrent blistering. Also reported during shodhana itself. Washing within 10 min removes about 50%; after 60 min, none. Oral overdose causes nausea, vomiting, abdominal pain.

04 Interaction matrix

Source column, verbatim: Not well characterised. Anacardiaceae cross-reactivity - patients allergic to cashew, mango, pistachio or poison ivy may react.
Normalised onto 0 canonical drug classes below.

No interaction edges recorded, and the constituent chemistry did not trigger any rule. That is an absence of data, not evidence of safety.
