Varshabhu

Names and identification

Language	Name
English	Varshabhu
Latin/Botanical	Trianthema portulacastrum L. (primary identity); also associated with Boerhavia erecta L.

Key Phytochemical Constituents

• Punarnavine and related alkaloids (Boerhavia species)
• Ecdysterone (insect molting hormone analog)
• Trianthenol
• Flavonoids, phenolics, and saponins
• Beta-sitosterol and stigmasterol
• Tannins and glycosides

How does it work?

• Diuretic activity through punarnavine-mediated modulation of renal tubular sodium-potassium ATPase
• Hepatoprotective effect via antioxidant enzyme restoration and membrane stabilization against chemical toxins
• Anti-inflammatory mechanism through inhibition of COX-2, LOX, and NF-kB signaling pathways
• Immunomodulatory action through macrophage activation and complement system modulation

Which traditional uses are supported by research?

These summaries come from the source notes, which do not name the studies behind them.

• Diuretic (Mutrala): traditionally used as a diuretic. Pharmacological studies have reported diuretic activity.
• Hepatoprotective (Yakrit-shodhana): traditionally used for the liver. Experimental studies have reported protection against chemically induced and paracetamol-induced liver damage.
• Anti-inflammatory and anti-edema (Shotha-hara): traditionally used for swelling and inflammation. Animal studies using carrageenan-induced paw edema and cotton pellet granuloma models have reported anti-inflammatory activity.
• Rejuvenative (Rasayana): traditionally used as a rejuvenative. Pharmacological studies have reported antioxidant, immunomodulatory and anti-aging activity.

Recent safety updates

• Identity confusion exists between Trianthema portulacastrum and Boerhavia species in the market; correct botanical identification is essential before use
• Trianthema portulacastrum in excess may cause hepatotoxicity; Boerhavia species are generally safer with established rasayana use; pregnant women should avoid both species
