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.
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.
There is no human clinical evidence on Thebu (Costus speciosus) in pregnancy or breastfeeding — only animal studies exist, and they are not a reliable substitute for human data. As a precaution, avoid use during pregnancy or while breastfeeding until more is known. If you take medicine for blood sugar, speak with your doctor first, as Thebu may add to its effect.
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.
Is Thebu safe in pregnancy or while breastfeeding?
There is no human safety data either way, only animal studies. As a precaution, we recommend avoiding Thebu during pregnancy or while breastfeeding until human data exists.
Grown in Sri Lanka and made under BRCGS, GMP, HACCP, FSSC 22000, and ISO 22000. Vegetarian capsule.
