Recommended therapeutic doses of turmeric range between 2 and 3 grams, states The Epicurean Digest. Curcumin, the active ingredient of turmeric, is available in capsule form.

Turmeric lowers blood sugar and blood pressure, states The Epicurean Digest. Taking the herb along with medications to lower blood sugar and/or blood pressure may result in excessively low blood sugar and/or blood pressure. Turmeric also enhances the effects of medications used to treat high cholesterol. Because turmeric is a blood thinner, it should not be taken in conjunction with chemical blood thinners.
