- In forests and swamps and near streams at low and medium altitudes.
- Found in Cagayan, Laguna, Rizal, and Bulacan Provinces in Luzon; in Bohol; and in Mindanao.
- Also occurs in India to China, in Taiwan, and southward to Sumatra and Java.
- Phytochemical screenings yield various types of sapogenins: quinovic acid, salicortin, saligenin, phenolic glycosides and pyrocatechol from the bark and leaves.
- Bark yields salicin.
- Plant yields tannins, triterpenes, viz., ß0amyrin, lupeol and chalcinasterol, steroids viz., ß-sitosterol and stigmasterol, with very low concentrations of free salicylaldehyde.
- Study of stem bark isolated 7 compounds: friedelin, 3 β-friedelinol acetate, β- sitosterol, β-sitosteryl-3-O-D-glucopyranoside, β-sitostenone, cis-1,2- cyclohexanediol, and long chain ester.
Bark considered febrifuge and analgesic.
Dried leaves reported to be cardiotonic and neurotonic.
- In India, the new flowers are lightly boiled and mixed with mashed potatoes.
- Bark used to treat fever.
- Used in Egyptian folk medicine as antirheumatic sedative and analgesic. Leaves and bark used as remedy for aches and fever.
- Decoction of leaf and root used for whooping cough in children.
- Paste of both leaf and root used externally for scorpion stings, bug bites, sores and warts.

- Used for making cricket bats and light furniture.
• 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. (2)
• 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. (3)
• Antibacterial / Insecticidal / Cytotoxicity: Extracts of leaves, bark, and roots were evaluated for antibacterial, insecticidal, and in vivo cytotoxic activities. Bark extract was active against all tested Gr+ and Gr- organisms. Root and leaf extracts showed insecticidal activity against Tribolium castaneum. In invivo cytotoxicity study, the root and bark extract showed moderate cell growth inhibition. (6)
• Cataract Prevention: Study showed Salix tetrasperma leaves extract prevents cataract progression in naphthalene- and galactose-induced cataract in animals. Vitamin E was used as reference drug. (8)
