Lodhra kashayo Tikto hima grahee Kaphapittahrit / Yoniroge vishesha ca -- Lodhra is astringent, bitter, and cold. It is Grahi (absorbent), reduces Kapha and Pitta, and is specifically indicated for Yoniroga (gynaecological conditions).

Classical documentation

Charaka Samhita documents Lodhra in the Stambhana (flow-reducing) herb group and in the context of Pradara (excessive discharge -- both menstrual and vaginal). Ashtanga Hridayam documents its use alongside Ashoka for complex Artava conditions where both excessive flow and quality impairment are present. Classical external use: Lodhra Churna as a Lepa (topical paste) for skin conditions, acne (Yuvana Pidika in classical terminology), and pore tightening -- a documented cosmetic application that has been validated by modern dermatological research on Symplocos bark tannin content.

Tannins and astringency
Lodhra bark contains up to 12% tannins (predominantly gallotannins and ellagitannins) -- the highest documented tannin content among major classical Ayurvedic bark herbs. Tannins produce astringency through protein precipitation -- binding to mucosal proteins and producing the tightening, flow-reducing effect documented as Stambhana in the classical system. The modern mechanism and the classical action description are precisely aligned.
Lotions and skin care
Lodhra is one of the primary classical herbs in Ayurvedic skin preparations -- Lodhra Churna mixed with honey or rose water as a Lepa (face paste) is documented for Mukharoga (facial skin conditions). Modern cosmetic formulations have incorporated Lodhra extract, and research has documented anti-acne and sebum-reducing properties consistent with classical external documentation.
