Origin & Discovery

First Documented

Sushruta Samhita (~300 BCE)

Kutaja's Latin species name antidysenterica reveals its primary use across cultures and centuries. Sushruta named it the foremost herb for grahani (irritable bowel) and atisara (diarrhea). The bark and seeds together — called Kutaja and Indrayava — form one of the most reliable anti-dysentery preparations in classical pharmacology.

Did You Know?

Conessine — the primary alkaloid — has documented activity against Entamoeba histolytica, the causative organism of amoebic dysentery.

Frequently Asked Questions

Kutaja for amoebic dysentery — does it work?

Yes — conessine has documented anti-amoebic activity, and Kutaja was used clinically in India for amoebic dysentery before metronidazole became standard. For confirmed amoebiasis, conventional medication is faster; Kutaja is excellent adjunct or for mild/recurrent cases.

Best Kutaja preparation for chronic IBS-D?

Kutajarishta (15-30 ml twice daily after meals) is the classical first choice for chronic IBS-D. Kutajaghana Vati is more concentrated for acute episodes.

Long-term safe?

Yes — well-tolerated for long courses. The high tannin content can occasionally aggravate vata constitutions; pair with warming carriers (ginger, fennel). Always investigate persistent diarrhea with appropriate medical workup.
