Sea buckthorn (Hipphophae rhamnoides) is a medicinal plant long used in herbal medicine. Available in supplement form, sea buckthorn extract contains a variety of essential fatty acids and antioxidants (including vitamin C, vitamin E and anthocyanins). Proponents claim that sea buckthorn offers a wide range of health benefits.
Uses for Sea Buckthorn
In herbal medicine, sea buckthorn has long been used to stimulate the digestive system, enhance heart and liver health, and treat skin disorders. Today, sea buckthorn is touted as a natural remedy for the following health problems:
Sea Buckthorn and Skin
In recent years, sea buckthorn oil has gained popularity as an ingredient in skin-care products. When applied topically, sea buckthorn oil is thought to moisturize the skin, ease irritation, treat acne and heal aging-related damage.
Benefits of Sea Buckthorn
There is currently a lack of clinical trials testing the effects of sea buckthorn. However, preliminary research suggests that sea buckthorn may offer a number of health benefits. Here's a look at several key study findings:
1) Sea Buckthorn and Eczema
Sea buckthorn supplements may help treat atopic dermatitis (a type of eczema), according to a 1999 study in the Journal of Nutritional Biochemistry. In tests on 49 people with atopic dermatitis, researchers observed significant improvement among those who took supplements containing sea buckthorn pulp oil every day for four months.
2) Sea Buckthorn and Wound Healing
Findings from animal-based research suggest that sea buckthorn may promote wound healing when applied topically. In a 2009 study in Food and Chemical Toxicology, scientists discovered that topically applied sea buckthorn seed oil helped speed up the healing of burn wounds in rats.
3) Sea Buckthorn and Diabetes
In a small 2010 study in the European Journal of Clinical Nutrition, researchers found that sea buckthorn may help keep blood sugar in check and protect against type 2 diabetes. In an experiment involving 10 healthy, normal-weight volunteers, the study's authors discovered that adding sea buckthorn berries to meals helped prevent a post-meal spike in blood sugar.
Is Sea Buckthorn Safe?
Since little is known about the safety of consuming sea buckthorn extract, it's important to consult your physician if you're considering the use of sea buckthorn supplements.
Sea buckthorn oil is not known to produce any adverse effects when applied to the skin.
Where to Find Sea Buckthorn
Available online, sea buckthorn supplements are sold in some natural-food stores. In addition, skin-care products containing sea buckthorn can be found in many specialty beauty shops.
Should You Use Sea Buckthorn for Health Purposes?
Given the lack of supporting research, it's too soon to recommend sea buckthorn for any health condition. It's important to note that self-treating a chronic condition with sea buckthorn and avoiding or delaying standard care may have serious health consequences.
