Thebu, the Sri Lankan sugar leaf

Last updated: May 2026

Thebu (Costus speciosus) is a leafy plant grown across Sri Lanka, traditionally eaten fresh or taken as a tonic to support healthy blood sugar. Our capsules concentrate the leaf into a measured daily dose, with 60 capsules per bottle.

What it traditionally supports

  • Healthy blood sugar already in the normal range.
  • Steady digestion.
  • Urinary comfort.
  • Everyday antioxidant support.

How to take it

Take 1 capsule a day before a meal. If you take medicine for blood sugar, speak with your doctor first, as Thebu may add to its effect.

Frequently asked questions

Is Thebu the same as the leaf people eat raw?

Yes. Many Sri Lankan households eat a Thebu leaf in the morning. The capsule is a measured, year-round way to keep the habit.

Can I take it with Gurmar or Cinnamon?

Yes, many people stack these for blood-sugar support. Keep your doctor informed if you are on medication.
