Licorice root can raise blood pressure, especially if used in excess. Those who have high blood pressure should avoid it. Many here have low blood pressure though. Sometimes I eat raw garlic, but sometimes I just use the powder.

Cayenne is also great for boosting blood flow, boosting metabolism, and fighting parasites. Cloves is great for fighting candida and parasites.

I mix curry powder with clove powder, garlic powder, cayenne powder, cinnamon, and black pepper, and often sprinkle plenty of this on my food.
