Background

Sea buckthorn (Hippophae rhamnoides) is a plant found throughout Europe and Asia. The leaves, flowers, seeds, and fruits are used as medicine.

Sea buckthorn contains vitamins A, B1, B2, B6, and C, as well as other active ingredients. It's been used traditionally to slow down the aging process.

People use sea buckthorn for burns, eczema, acne, indigestion, high blood pressure, wrinkled skin, and many other purposes, but there is no good scientific evidence to support most of uses.

Don't confuse sea buckthorn with other plants known as "buckthorn," including alder buckthorn, European buckthorn, and Cascara sagrada. These are not the same.
