Jarpal in other languages
Introduction
Jarpal, better known as Jayapala (Croton tiglium), is the purging croton — a small tree whose seed yields one of the most violent purgatives known.
Ayurveda classes it among the Upavisha and uses it only after Shodhana, in doses measured in single grains, inside classical compounds for obstinate constipation and abdominal swelling.
Classification
Family Euphorbiaceae. The seed and its oil are officinal, only after Shodhana. Rasa: Katu. Guna: Laghu, Tikshna, Ushna. Virya: Ushna. Vipaka: Katu. Doshaghnata: pacifies Kapha and Vata; strongly aggravates Pitta.
Uses & benefits
Used in obstinate constipation, ascites and abdominal masses where a drastic downward clearing is required, and in some classical preparations for skin disease. In this catalogue it appears in Kaishor Guggulu, where it is one small purgative element within a large compound.
Jayapala as a drastic purgative
Reserved for cases where gentle purgatives have failed, and always given within a formulation that moderates its violence.
Why the dose is so small
A single purified seed is a full dose in classical practice. The margin between effect and harm is narrow, which is why it is never self-selected.
Dosage — how much to take
Strictly as prescribed. Purified seed in doses of 15–30 mg within a compound. Never taken alone.
Dosage varies with age, constitution and condition — confirm with a qualified Vaidya.
