What is Rosehip Herb? It is a deciduous shrub with pale to pink flowers followed by scarlet round to ovoid hips (the fruit).
The fruits of Rosa canina are used for colds, influenza, scurvy, gastritis and to control diarrhea, while the fruits from Rosa laevigata are used to treat urinary dysfunction, infertility, chronic diarrhea and to regulate kidney function.
The oil extracted from Rosa rubiginosa has excellent tissue regeneration properties and helps to reduce scars (trauma and surgical), as well as reducing wrinkles - see essential oil use below.
Apart from the moisturizing, soothing, and softening effect that it has, it furthermore contains polyunsaturated fatty acids (vitamin F) also known as essential fatty acids (EFA), and when they are absorbed through the skin, they convert to prostaglandins (PGE), which are involved in cellular membrane and tissue regeneration.
Rosehip oil brings about skin regeneration and wound healing. It contains trans-retinoic acid, which is responsible for skin rejuvenation and quickens healing. It repairs skin subjected to excessive sunlight and resultant photoaging.
The linoleic and linolenic acids in rosehip have also been shown to reduce pigmentation of the skin and when used regularly it has been shown to reduce fine lines and wrinkles.
Aromatherapy and essential oil use
Although rosehip oil is not strictly an essential or volatile oil, it is normally classified as an essential oil, as it is far more than just a vegetable carrier oil into which essential oils are normally mixed.
Rosehip oil does not need to be diluted before use on the skin as most essential oils need to be, and has some very positive effects on the health of the skin.
It has some great rejuvenating properties and is helpful with fighting sun damage to the skin. It is high in GLA, helping to reduce the signs of aging, especially the fine lines around the eyes (crows' feet) and lines around the mouth, fighting the drying effects of the sun and climate, as well as assisting with attenuating both accidental and surgical scars.
It helps the skin heal and regenerate, preventing the formation of ugly keloid scar tissue (thickening of the skin when forming scar tissue) and is helpful in healing burns, scars, and stretch marks.
