This Ginger relative was originally native to East Asia through India, Bangladesh, Assam and Mayanmar, but now Plai (aka Banglai; Zingiber montanum, syn. Zingiber cassumunar) has become invasive in other tropical regions of the Caribbean and South America.
Plai has uses mainly for its essential oil, but also in foods as a condiment, especially in Thailand.
The essential oil of Plai mainly consists of monoterpenes and monoterpenols, such as sabinene and terpineol, and in massage and topically Plai is used for pain and inflammation, specifically for treating bruising, sprain and muscular pain.
In scientific investigation, Plai has been found to exhibit analgesic, anti-inflammatory and antimicrobial properties. In a systematic review of clinical studies, Plai treatment showed benefits for reduction in pain of muscles, as well as ankle sprain.
Plai is also used for treatment of acne vulgaris, respiratory and antibacterial support and also for its reported anti-histamine effect. In aromatherapy, Plai is not only used for pain, but also is energizing and helpful in blends for colds.
In a recent phase 3 randomized clinical study on the effects of Plai on allergic rhinitis, it was found safe with improvements in rhinorrhea, itchy nose and itchy eyes.
