Species within the Blumea genus are widely distributed across tropical regions of Asia, Africa, and the Pacific, with the highest diversity observed in the tropical Asian region. In recent decades, researchers have concentrated their efforts on studying the species within the Blumea genus that are used in components of the Ayurvedic traditional medical system in India and traditional beverages known as "Loloh". 4 In China, B. balsamifera is utilized as a fragrance due to its high essential oil content. Its entire plant or leaves are employed in traditional Chinese medicine to treat various conditions, including scabies, dermatitis, beriberi, back pain, menstrual pain, arthritis, skin injuries, and even in the formulation of insect repellents. 5 In Thailand, dried leaves of B. balsamifera can be used to make medicinal cigarettes to alleviate symptoms of sinusitis, abdominal pain, and cough, and can even be combined with other plants to create postpartum herbal baths for women. In the Philippines, B. balsamifera serves as a traditional remedy for kidney stones, common colds, and diuretic purposes. Furthermore, in other Asian countries such as Malaysia, B. balsamifera is also incorporated into Ayurvedic traditional medicine systems. 4 While there have been some studies related to the pharmacological effects of B. balsamifera, the safety of ethanol extract from Blumea balsamifera leaves (EEBB) in vivo remains unconfirmed. Based on the traditional use of B. balsamifera, this study was conducted to comprehensively assess the acute and subchronic toxicity of EEBB on an animal model. The results of this research will provide a foundation for utilizing this extract in research and applications for the treatment of arthritis, pain relief, and cancer prevention.
