I've taken Sea Buckthorn oil before and it's great for the skin. Oil made from the berry is orange, while oil made from the seed is a very light yellow. Of course it's the oil from the berry that's best for the skin (also great for healing the intestinal lining). You can get a fabulous, clean organic Sea Buckthorn Oil at http://www.bluesagenaturals.com.
I wouldn't oil pull with it though. (Just started and am using an organic, cold pressed sesame seed oil which seems to be detoxing me nicely so far...)
