Botanical Overview
Red Saunders (Pterocarpus santalinus) is a flowering plant in the Fabaceae family. Traditional medicine systems have documented several valuable applications for this species, supported by its observed therapeutic effects. The legume family (Fabaceae) includes trees, shrubs, and herbs that produce pods (legumes) and form nitrogen-fixing root nodules through symbiosis with bacteria. The flowers are typically pea-shaped with five petals. This large family provides food staples, timber, and numerous medicinal species.

General Description
It is known for its red colour and has been used for furniture, musical instruments, and traditional herbal medicine. Because of the high market value for its timber, the species has been overexploited, and illegal trade remains a problem. It is listed as Near Threatened on the IUCN Red List. It should not be confused with the aromatic Santalum sandalwood trees native to southern India.

Traditional Uses
Red Saunders has been traditionally used for digestive health, skin and wound care, and urinary tract health, among other applications.
Digestive health.
- Dysentery
- Diarrhea
- Ache(Stomach)
For digestive complaints, the herb is typically prepared as a tea or decoction taken before meals. The bitter compounds stimulate digestive secretions and improve nutrient absorption. Some traditions use the powdered root or leaves in small doses as a stomachic tonic.
Skin and wound care.

Urinary tract health.
- Diuretic
Urinary tract applications typically involve drinking the herb as a mild tea, which increases urine production and helps flush the urinary system. It may be combined with other demulcent herbs to soothe irritated tissues.
