Will Herbs Lower Normal Cholesterol?

I use turmeric, rosemary, garlic, and thyme (I make it myself). Will this lower normal cholesterol? I use about two veggie caps, mostly turmeric and thyme.

Turmeric is used to lower cholesterol. Medicinal dosage is 1 - 2 grams daily. Garlic raises HDL (the good cholesterol), and lowers total cholesterol after a fatty meal. Medicinal dosage is 1500 to 3000 mg, twice daily. Thyme and Rosemary are not known to lower cholesterol.
Capsules may contain 200 to 500 mg of herb. At this dosage, you may not get a cholesterol-lowering effect.
