Raw garlic is probably the best single spice to fight candida. Ginger, cayenne,cloves and cinnamon are also good. I mix garlic powder, ginger powder, cayenne powder,cinnamon, clove powder, and some other spices and put it on my food.

I guess cassia might be an issue if you take more than a teaspoon a day. According to wikipedia, a teaspoon of cassia has between around 6 and 12 mg of coumarin, and the German government recommends a maximum intake of 0.1 mg per kg of body weight.

I guess cloves should be taken at less than 2 teaspoons a day, and for longer term use no more than a teaspoon a day.

Cayenne increases blood flow, and speeds up the metabolim. It is also very antiparasitic.
