Premna odorata

Premna odorata (Blanco) is traditionally brewed as a mild tea by the Khasi people of Meghalaya, India, where the dried leaves are steeped in hot water for 10 minutes to relieve cough and colds (Singh et al., 2018). The same leaf infusion is used by the Bodo community of Assam to treat fever and as a poultice for skin infections (Boro et al., 2017). In the Philippines, the Tagalog people prepare a decoction of the fresh leaves in water for 15 minutes to reduce inflammation and to aid wound healing (Santos et al., 2015).

**Recipe – Mild leaf tea**
Take 5 g of dried Premna odorata leaves and add them to 250 ml of boiling water. Let the mixture steep for 10 minutes, strain, and drink warm. Use no more than 3 cups per day. Pregnant or nursing women should avoid this tea until a qualified practitioner confirms safety, as the plant contains compounds that may affect uterine activity.

**Active constituents**
Analyses of Premna odorata leaves have identified flavonoids such as quercetin and luteolin, along with phenolic acids like rosmarinic acid. These compounds are known for their anti‑inflammatory and antimicrobial properties, which likely underlie the plant’s traditional use for cough, fever, and wound care.

**Modern relevance**
Recent phytochemical studies confirm the presence of these bioactive molecules, and the plant is now available as a herbal supplement in several Asian markets, continuing its role in both traditional and contemporary health practices.
