Evening primrose oil was given through a intragastric catheter in dose of 50 mg/kg day for 10 days to pregnant (8 animals) and nonpregnant (8 animals) rabbits. Control groups contained 8 pregnant and 8 nonpregnant animals. In the acute experiment we estimated directly (intraarterially) basal blood pressure and pressor response to angiotensin II (A II). The systolic and diastolic response to A II was significantly lower in pregnant rabbits which received evening primrose oil compared to control group. No significant effect was found in the nonpregnant groups. Basal (before A II) systolic and diastolic blood pressure did not differ between the treated and untreated subject in each group.

There is a growing need for safer alternatives to synthetic additives commonly used in lipophilic carriers for products such as foods, pharmaceuticals, personal care items, and cosmetics. Natural antioxidants, which prevent lipid peroxidation while providing additional health benefits, offer a promising solution. Evening primrose oil, a rich source of antioxidant compounds with numerous biological benefits, emerges as a potential natural preservative for oil-based products.

Hormone replacement therapy (HRT) used to treat hot flashes has side effects, such as an increased risk of coronary heart disease and breast cancer. There are ongoing controversies regarding the risk of ovarian cancer associated with HRT. HRT is best avoided in conditions such as liver or gallbladder disease and gastrointestinal disorders.

This study aimed to evaluate the oxidative stability and surface properties of cold-pressed vegetable oils using the Langmuir monolayer technique. Six oils-milk thistle, evening primrose, flaxseed, camelina sativa, black cumin, and pumpkin seed-were analyzed to investigate their molecular organization and behavior at the air/water interface, particularly after undergoing oxidation. The results showed that oils rich in polyunsaturated fatty acids (PUFAs), such as flaxseed and evening primrose oils, formed monolayers with larger molecular areas and lower stability, which led to faster oxidative degradation, especially under thermal conditions.

The pathogenesis of atopic dermatitis (AD) points to skin barrier dysfunction as a critical piece of the puzzle. Deficiencies in fatty acids and ceramides-key elements of the skin barrier-have been linked to AD. Fatty acids can be separated into omega-3 and omega-6, which can be found in a variety of foods such as fish, nuts, seeds, and even plants.

Chronic pruritus, or persistent itching, is a debilitating condition that severely impacts quality of life, especially in palliative care settings. Traditional treatments often fail to provide adequate relief or are associated with significant side effects, prompting interest in alternative therapies. This review investigates the antipruritic potential of eight medicinal plants: chamomile (), aloe vera (), calendula (), curcumin (), lavender (), licorice (), peppermint (), and evening primrose ().
