Studies
• Anti-Inflammatory: A study of extracts of five plants abundantly growing in Egypt, including Salix tetrasperma, revealed anti-inflammatory activity of the extracts under investigation. Activity was attributed to flavonoids.
• Cardiotonic: Aqueous extract of dried leaf reported to possess cardiotonic activity.
• Reverse Transcriptase Inhibition: Methanol extract of dried leaf exhibit reverse transcriptase inhibition effect.
• Diuretic / Laxative: Study of aqueous extract of Salix tetrasperma in albino rats showed significant diuretic activity as well as laxative activity in a dose-dependent manner.
