Sida alba L. (sometimes classified under Sida spinosa or Sida rhombifolia depending on regional taxonomy, with which it shares synonyms) is an annual or perennial herb, commonly referred to as White Fanpetals, Spiny Sida, or White-flowered Sida. It is widely recognized for its extensive use in traditional medicine across Africa, Asia, and the Americas.
Spiny sida (Sida spinosa, of which Sida alba is a synonym, family Malvaceae) is a small, much-branched herb or subshrub, 20 cm to 1 metre tall. It is named for the small, spine-like points at the base of its leaf stalks. Its toothed leaves are small, and it bears small pale yellow flowers, singly or in small groups where the leaves join the stem. It belongs to the same family as cotton, okra and hibiscus.
It grows throughout the seasonally dry tropics and subtropics, in Africa, Madagascar, the Middle East, the Indian subcontinent, Latin America and the Caribbean, and it has been carried to many other places. It typically grows in disturbed ground, such as roadsides, pastures and farmland, where it is often treated as a weed.

Leaves, roots, and stems are used to treat respiratory issues, infections, fevers, malaria, skin diseases, digestive problems, and reproductive health concerns, with anti-inflammatory and analgesic effects.
Leaves are sometimes eaten as a condiment or vegetable and brewed as a tea substitute with mild stimulant properties.
Sida alba is used in spiritual cleansing, while its stems are made into brooms believed to disinfect spaces symbolically, though caution is advised due to ephedrine content.
The plant is primarily propagated by seeds, though stem cuttings can also be used, thriving in full sun to partial shade on well-drained soil.
