Garlic (Allium sativum) vs Goldenseal (Hydrastis canadensis)

Garlic (Allium sativum)

Goldenseal (Hydrastis canadensis)

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.

Goldenseal (Hydrastis canadensis) is a low-growing North American perennial, recognized by its thick yellow root and a short erect stem up to about 1 ft (30 cm). Native Americans historically used goldenseal for digestive disorders, wounds, skin and eye conditions, and cancer, and NCCIH says it is promoted today for colds and other upper respiratory infections, hay fever, diarrhea and constipation. NCCIH says there is not enough evidence to know whether goldenseal helps any health condition.
