Museum of Natural Medicines



Thailand has been known for its abundance of herbs and plants, which are great natural providers for our four basic human needs, one of which is medicine. Herbal and traditional medicines have long been used to treat illnesses. Medicinal formulas have been handed down from generation to generation in both written and by oral tradition. Unfortunately, they are now disappearing because the younger generation has lost their interest in this branch of science. Thus, conservation of this traditional knowledge would be beneficial to those who are interested and would efficiently support the natural product research in drug discovery.

Over the past 100 years, Faculty of Pharmaceutical Sciences and several faculty members in the Department of Pharmacognosy and Pharmaceutical Botany have gathered herbs, tools for pharmacists, and knowledge in natural medicine for their teachings and researches. Faculty of Pharmaceutical Sciences has therefore inaugurated the Museum of Natural Medicine, where these collections are now publicly displayed. On March 26th. 2001, HRH Crown Princess Mahachakri Sirindhorn presided over the opening ceremony of the new Osotsala building and paid the first royal visit to the museum.


The objectives of the museum

1.       To collect, conserve, and display herbal specimens of Thailand and other countries as well as ancient tools for preparing medicines.

2.       To provide academic references and knowledge of herbal and natural medicines, to characterize and identify herbs so as to give the public accurate information in distinguishing adulterants or impurities in herbal medicines and herbs of poor quality.

3.       To serve as a self-learning center for students in both formal and non-formal education and a resource center for visitors who are interested.
