Botanical Overview
Broomweed (Sida rhombifolia) is a flowering plant in the Malvaceae family. The traditional uses of this species reflect its genuine medicinal value, validated by generations of practical experience. The mallow family (Malvaceae) includes herbs, shrubs, and trees with alternate leaves, often with stellate hairs. The flowers are typically showy with five petals and numerous stamens fused into a column. Many species produce mucilage and have demulcent and emollient properties.
General Description
Other common names include rhombus-leaved sida, Paddy’s lucerne, jelly leaf, and also somewhat confusingly as Cuban jute, Queensland-hemp, and Indian hemp (although S. rhombifolia is not closely related to either jute or hemp). Synonyms include Malva rhombifolia. It is used in Ayurvedic medicine, where it is known as kurumthotti.

Traditional Uses
Broomweed has been traditionally used for digestive health, skin and wound care, and urinary tract health, among other applications.
Digestive health.
- Dyspepsia
- Diarrhea
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.
- Boil
- Wound
- Skin
For skin conditions, the fresh or dried plant is applied topically as a poultice, wash, or compress. A strong decoction can be used to clean wounds and sores. The antimicrobial properties help prevent infection while promoting tissue repair.
Urinary tract health.
- Diuretic
- Bladder
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.
