Abhaibhubejhr Day Spa

Abhaibhubejhr Day Spa is the treatment wing of Chao Phraya Abhaibhubejhr Hospital, Thailand’s leading public hospital for traditional medicine — a working part of the hospital campus in Prachin Buri, not a standalone resort spa. Entry to the hospital grounds, museum, and pharmacy is free; the spa treatments themselves are paid services, priced by package rather than a fixed rate, and run Wednesday to Sunday, 09:00-20:00.

The hospital’s original building, a two-storey Baroque-style structure completed in 1909, was ordered by Chao Phraya Abhaibhubejhr (Choom Abhaiwongse), then governor of Phra Tabong province, as a possible residence for King Chulalongkorn during a planned visit that never happened — the king died in 1910 before it was finished. King Vajiravudh used it instead, later giving the land to build what became Prachin Buri’s hospital. The building was listed as a historic monument by the Department of Fine Arts in the 1990s, and the hospital opened it as the Thai Herbal Medicine Museum in 1994. It now houses that museum alongside the hospital’s original herbal pharmacy, where staff still weigh out prescriptions from wooden drawers of dried herbs. A retail shop next door sells the same herbal balms, soaps, and tonics used in treatments, with part of the profit funding the hospital’s charitable foundation.

Massage sessions start with a blood-pressure check before you’re shown to the treatment room — the main hall holds twenty mattresses under Thai-silk covers. Therapists work traditional pressure-point and stretching techniques, and the herbal compresses are packed with lemongrass, turmeric, and galangal grown for the hospital’s own formulations rather than bought in bulk. The beauty side of the menu adds facials and body scrubs using the same herbal bases. Next door, the Spa Kitchen restaurant serves “clean food” built around the hospital’s herbal ingredients — mains run 60-100 THB, snacks about 40 THB, open daily 08:00-17:00.

Insider Tip: Pair a treatment with a walk through the museum and pharmacy — they’re free, and seeing where the herbal formulas actually come from makes the treatment afterward mean more than a generic spa visit would.

Watch out: the free museum and pharmacy close by around 16:00, well before the spa’s 20:00 finish — don’t save them for after a late-afternoon treatment or you’ll miss them.
