About

Garlic (Allium sativum) is a bulbous perennial in the onion family, recognized for its sharp flavor and characteristic odor. It is widely used in cooking, and crushed fresh garlic contains allicin. NCCIH says garlic supplements may lower cholesterol, blood pressure and blood sugar to a small extent, but very little research has tested claims that they boost immunity.

Horseradish (Armoracia rusticana) is a robust perennial with a thick, pungent taproot, large crinkled leaves, and clusters of white flowers. It is known for its strongly spicy flavor.
