Sanay in India
This shrub, known as हिन्द सना Hind-sana (Hindi), Alakalam (Tamil), nelaponna (Telugu), ಸೋನಾಮುಖಿ Sonamukhi (Kannada), സൊനമുക്കീ Sonnamukki (Malayalam), Bhitarvada (Marathi), is the source of the classic senna leaf and pod. Senna alexandrina is cultivated across Gujarat, Tamil Nadu, Rajasthan, Andhra Pradesh, Karnataka, particularly in Tamil Nadu's Tirunelveli region, long a major senna-growing centre.
Uses
Its dried leaves and pods have a long history of traditional use as a natural laxative in both Ayurveda and other traditional medicine systems worldwide — an attributed traditional use, not a medical claim, and not for casual or prolonged use without guidance.
How to Identify Sanay
A shrub with pinnate leaves made of several pairs of narrow, pointed leaflets. Bright yellow flowers cluster loosely at the stem tips, followed by broad, flat, papery pods that dry to a pale brown.
