May have anticancer effects and other benefits

Flavonoids and antioxidants, which are present in sea buckthorn oil, may have anticancer properties. For instance, the flavonoid quercetin, which is abundant in sea buckthorn, appears to aid in the death of cancer cells. Other antioxidants found in sea buckthorns, such as carotenoids and vitamin E, may also be protective. The spread of cancer cells may be halted by sea buckthorn extracts, according to a few test-tube and animal experiments. Animal studies further support the idea that sea buckthorn may protect healthy cells from the side effects of radiation, a popular cancer treatment.

Sea buckthorn may reduce vaginal drying and act as an effective alternative treatment for postmenopausal women who cannot take estrogen. One study linked daily sea buckthorn intake to reduced eye redness and burning. Sea buckthorn contains small amounts of lecithin, a type of fat that may remove excess oil from your hair. It may also help repair damaged hair and restore its elasticity.
