Description: Tithonia diversifolia, commonly known as the Mexican sunflower or tree marigold, is a perennial shrub that can grow up to 3 meters tall. It has hollow, woody stems and large, deeply lobed leaves that are ovate to obovate, with upper leaves measuring between 6-23 cm long and 3-18 cm wide. The plant produces bright yellow daisy-like flowers with both ray and disc florets​​​​.

Distribution and Habitat: Native to Mexico and Central America, Tithonia diversifolia has become naturalized in various tropical and subtropical regions worldwide. It thrives in seasonally dry tropical climates and prefers well-drained soils. The plant is moderately drought-resistant and can grow in both full sun and partial shade conditions. It is often found along roadsides, in abandoned fields, and in disturbed areas​​​​.

Medicinal Properties: Tithonia diversifolia is valued for its medicinal properties. Its leaves contain sesquiterpene lactones, which have been shown to possess anti-inflammatory, antimicrobial, and antimalarial activities. Extracts from the leaves have been used to treat gastrointestinal infections, skin diseases, and urinary tract infections. Additionally, studies have indicated that T. diversifolia has potential antidiabetic and antihyperglycemic effects, as it has been found to lower blood glucose levels in experimental settings​​​​.

Toxicity: While Tithonia diversifolia has numerous medicinal benefits, caution is advised due to potential toxicity. Some studies have reported that high doses of leaf extracts can cause kidney and liver toxicity, although these effects were reversible. It is important to use the plant under professional guidance to avoid adverse effects​​​​.

Additional Uses: Beyond its medicinal applications, Tithonia diversifolia is also used in agriculture and horticulture. It can be utilized as green manure, improving soil fertility by adding organic matter and nutrients, particularly phosphorus. The plant is also employed for erosion control, as fodder for livestock, and as a source of fuelwood. Its bright flowers make it a popular ornamental plant in gardens and landscapes​​​​.
