Bhilawa in other languages
Introduction
Bhilawa (Semecarpus anacardium) is the marking nut, so called because its caustic black juice was used to mark cloth in laundries. The fruit is the drug.
Ayurveda classes it among the Upavisha and uses it, after Shodhana, as a powerful Rasayana and Vata drug. Unprocessed, its resin raises severe blisters on contact.
Classification
Family Anacardiaceae. The fruit is officinal, only after Shodhana. Rasa: Katu, Tikta, Kashaya. Guna: Laghu, Snigdha, Tikshna. Virya: Ushna. Vipaka: Madhura. Doshaghnata: pacifies Kapha and Vata; strongly aggravates Pitta.
Uses & benefits
Used in Amavata and chronic Vata disorders with pain and stiffness, in chronic skin disease, and as a Rasayana in classical preparations taken under supervision. It appears in Prasarini Taila in this catalogue.
Bhallataka in Amavata
Its penetrating heat is used in rheumatic pain with stiffness where cold, heavy Vata-Kapha conditions have not responded to gentler drugs.
Bhallataka as a Rasayana
Classical texts describe a Rasayana use, always in purified form and under close supervision because of its heat and irritancy.
Dosage — how much to take
Strictly as prescribed. Purified fruit in doses of 125–250 mg within a compound, usually with milk or ghee to temper it.
Dosage varies with age, constitution and condition — confirm with a qualified Vaidya.

When should Bhilawa be avoided?

Even purified, it strongly aggravates Pitta and can cause burning, mouth ulcers and skin eruption. Contraindicated in pregnancy, breastfeeding, children, and in anyone with a Pitta-dominant or inflammatory condition. Handle raw material with gloves only.
Where does Bhilawa grow?
A deciduous tree of dry forest across India, common in the sub-Himalayan tract, central India and the Western Ghats.

Frequently asked questions
Why does Bhilawa burn the skin?
The nut shell contains a phenolic resin closely related to the irritant in poison ivy. Contact with unprocessed material causes painful blistering.
Can it be taken as a Rasayana at home?
No. The classical Rasayana use requires purified material, precise dosing and supervision, because the margin between benefit and harm is narrow.
