Plai (Cassumunar Ginger)
Zingiber cassumunar
Long before it found its way into spa menus abroad, plai was the backbone of Thai traditional medicine, its knobby golden rhizome pounded fresh and rubbed into aching limbs by generations of village healers. It is the herb behind luk pra kob, the fragrant herbal compress balls that traditional Thai massage therapists steam and press along tired muscles, and it has traditionally been used to help new mothers recover after childbirth, wrapped warm against the belly and back. Traders once carried the dried rhizome along Southeast Asian trade routes precisely because its reputation for easing strains and stiffness traveled as well as the root itself. Even today, in Thailand it remains a household name, as familiar in a family's medicine basket as ginger is in a Western kitchen.

Traditional preparations.
The classic Thai preparation, an infused oil traditionally massaged into sore, tired muscles after a long day or a hard workout.
Traditionally, thin slices of fresh or dried plai rhizome are gently warmed in a neutral carrier oil, such as sesame or coconut oil, over low heat for about 20 minutes, then strained and cooled before massaging a small amount into the skin.
A bundled compress of pounded plai and companion herbs, steamed and pressed along the back and limbs in traditional Thai massage.
Traditionally, pounded fresh plai rhizome is wrapped in cloth with a small handful of companion herbs like turmeric and lemongrass, steamed until warm and fragrant, then pressed gently against sore areas once cool enough to touch comfortably.
Safety.
Plai is traditionally used externally as a massage oil or compress rather than swallowed, and it is not established as safe to eat. It can irritate sensitive or broken skin, so patch test first and keep it away from eyes and mucous membranes.
