Digestive comfort and dyspepsia

Limited Evidence

Small Indonesian trials of Curcuma xanthorrhiza extract suggest improvements in functional dyspepsia symptoms. Independent replication outside Indonesia is limited.

How it works

Javanese turmeric contains curcuminoids (including curcumin and the distinctive xanthorrhizol) and essential oils. Xanthorrhizol is a unique sesquiterpene with anti-inflammatory and possible hepatoprotective activity in preclinical studies. Clinical research is more limited than for common turmeric, but available studies suggest similar antioxidant and anti-inflammatory profiles. Some Indonesian trials have explored use in dyspepsia, liver function, and joint discomfort.

Dosage

Traditional jamu doses use 5 to 10 g of fresh rhizome or 0.5 to 2 g of dried powder per day. Extract supplements are dosed by curcuminoid or xanthorrhizol content.

When and how to take it

Javanese turmeric can be taken with meals to support absorption and reduce stomach upset. Time of day is not critical.
