Note(s)This section has been translated automatically.

Evening primrose (seed) oil is very sensitive to oxidation due to its numerous unsaturated fatty acids. Hence, an addition of an antioxidant (e.g. BHT = butylhydroxytoluene [see also active agents, photoinstable] in a 0.05% concentration is recommended. Alternatively, alpha-tocopherol 0.05-0.1% should be used.

Evening primrose (seed) oil is comparatively expensive. It can be replaced by hemp oil (see below cannabis) or borage seed oil.

In epilepsy, temporal lobe seizures may occur, especially in patients with schizophrenia. Caution in patients with known epilepsy!

Strict indication in pregnancy!

Not recommended for children under 12 years of age.
