What is Omega-7? Omega 7 may help to maintain natural lubrication during the menopause, via its soothing action on mucous membranes such as those of the V*****L tract. Omega-7 is a nutritional supplement prepared from berries of the sea buckthorn plant (Hippopae rhamnoides), a shrub originating in the Himalayas. Most of the research into the sea buckthorn plant has been carried out by Chinese and Russian scientists, and sea buckthorn is widely used in health products and cosmetics in these countries. More recently, the beneficial potential of the sea buckthorn plant has been increasingly recognized in Europe and North America.
