I accept due utility described, one capsule fasting together with domestic fish oil. sometimes puncture kapsulki 1 and add to the mixture of base oils for the face, as Evening primrose is known for its moisturizing properties and antikuperoznymi. I consider optimum dosage - a capsule 1 ml, which is about 20 drops. a mixture of mustard oil, neem and primrose helps with brittle nails, hair loss, dandruff, although these afflictions helps any oil - the main thing is not to be lazy and use regularly. visible super-effect there, but I believe that somewhere in there it works)))
