Breast pain (mastalgia), breast cysts
Evening primrose oil is a popular treatment for breast pain in Europe. However, there are no high-quality scientific studies showing that it works. Studies of evening primrose oil for breast pain have yielded unclear results. Therefore, it cannot be recommended for either of these conditions.


Potential Dangers


Allergies


People with allergies to plants in the Onagraceae family may be allergic to evening primrose oil. People allergic to gamma-linolenic acid or any other ingredients in evening primrose oil should avoid its use. Contact dermatitis (skin rash) is possible.


Side Effects


There are reports of seizures with the use of evening primrose oil. People at risk of seizures should avoid using it. Evening primrose oil lowers blood pressure in animals, but effects in humans are not clear. Headache, stomach pain, nausea and loose stools may occur.


Pregnancy And Breast-Feeding


There is not enough information available to know if evening primrose oil is safe for pregnant or breast-feeding women.




Interactions


Interactions with drugs, supplements and other herbs have not been thoroughly studied. The interactions listed below have been reported in scientific publications. If you are taking prescription drugs, speak with a health care professional or pharmacist before using herbs or dietary supplements.


Interactions With Drugs


Evening primrose oil may cause seizures when taken with phenothiazine drugs such as chlorpromazine (Thorazine), thioridazine (Mellaril), trifluoperazine (Stelazine) or fluphenazine (Prolixin). There is a risk of seizure when used with anesthesia, and you may need to stop taking evening primrose oil before some surgeries. Patients taking drugs that increase the risk of seizures or drugs that prevent seizures should avoid evening primrose oil. In theory, this herb may add to the blood pressure-lowering effects of other drugs. Ask a health care professional or pharmacist for advice before you take evening primrose oil if you are taking any other drugs.


Interactions With Herbs And Dietary Supplements


The possibility of harmful effects when taking evening primrose oil with other herbs or supplements has not been well studied. Always read labels carefully, and speak with a health care professional before starting new therapies.

they normally contain evening primrose and vitamin E, and if you have pre-menstrual or during menstrual symptoms then its meant to be great, regardless of your age.

yup, i've been taking vitamins for hormone balance for a few years now. evening primrose is fantastic for pmt and related issues. also vit b6, magnesium and zinc are good supplements. you won't be asked any questions at all, 17 is a totally acceptable age to be taking evening primrose oil!

I'm 17, I take it once-a-day and find it does wonders.

When I first went on the pill I had really bad mood swings. My doctor suggested evening primrose oil and it really did work. It also makes my periods much lighter and less painful. It sorts out those hormones!
