Jayapala Shodhana – Purification of Jamalgota seeds:
जयपालं त्वग्रसजारहितं पोट्टलीगतम् ।
ढोलायन्त्रे तु यामैकं स्वेदयेत् गव्यदुग्धतः ।।
संपेष्य खल्वे मूलेषु खर्परेषु प्रलेपयेत् ।
विज्ञाय विगतस्नेहं जयपालं समाहरेत् ।।                        (र.त)
Ayurveda mentions about the shodhana (purification) method to purify Jayapala seeds before its use. The shodhana method is done to reduce the toxicity of the seeds.

Research articles related to Croton tiglium:
Anti-helminthic activity: The objective of the study was to test the anthelmintic activity of aqueous and petroleum ether extracts of Croton tiglium seeds. The activity was checked in aqueous and petroleum ether extracts at three different concentration (25, 50 and 75mg/ml) and results were expressed in terms of paralysis time and death time for worms. The results were compared with standard solution, Albendazole (20 mg/ml & 40mg/ml). Both the extract showed significant anthelmintic activity.

Gastro intestinal effect: Croton tiglium used as a cathartic in Ayurvedic system of indigenous medicine, was investigated for its effects in experimental animals. The extract exhibited a dose dependent cathartic effect in albino rats, the extract also showed an increase to gut movement with an increased contractile movement on rabbit jejunum, partially blocked by atropine these preliminary findings suggest that the ethanol extract of the croton dried nuts elicit a purgative effect by increasing the gut motility, partially via muscarnic receptor activation.

Anti- dermatophytic activity: Investigations were carried out in this study to evaluate the anti- dermatophytic activity of the stems, leaves, and seeds of Croton tiglium. The anti- dermatophytic activities of the extracts were evaluated by disc diffusion and microdilution susceptibility assays against Trichophyton mentagrophytes, T. rubrum, and Epidermophyton floccosum. The ethanolic extracts of stem or seed of C. tiglium exhibit strong anti- dermatophytic activities and, thus, could be considered for application on treating skin fungal infections after appropriate processing.
