Rosehip Seed (Rosa rubiginosa)
Description: Rosa rubiginosa, also known as sweetbriar rose, is a wild deciduous shrub that is native to Europe and western Asia. This dense shrub grows to around 2 meters high and across with stems that have many hooked prickles. The foliage has a strong apple-like aroma, with pinnate leaves and flowers that are produced in clusters of 2 to 7 blooms. Rosehip seed oil is also produced from Rosa canina, also known as the dog rose. This wild deciduous shrub is native to Europe, northwest Africa and Western Asia. This shrub is around 1 to 5 meters in height, and is covered in small sharp, hooked prickles. Its flowers are generally pale pink, but can vary between a deep pink and white.
History Folklore: Tea made from the hips of the Sweetbriar rose is very popular and considered by many to be a healthy way to get their daily dose of vitamin C. During the second World War, the British relied on rose hips and hops as their sources of vitamins A and C. In Chile and Argentina it is known as “Rosa Mosqueta” and is found growing wild around the Andes. This species is an invasive species in southeast Australia.
During the second World War, Rosa canina was planted in Victory Gardens throughout the United States. It’s flower is one of the national symbols of Romania.
Rosehips contain a high concentration of vitamin C ranging from 0.24 – 1.25%. Rosehips are mainly used as a source of natural vitamin C. They are also widely used as a herb tea ingredient, or in capsules and tablets as a source of vitamin C. (Leung, Foster).
Harvest: The hips are left on the plant and generally harvest a week after the first frost. They should then be processed as soon as possible after harvesting.
Extraction: A golden, reddish colour oil is cold pressed from the seeds of the fruit of the wild rose bush. The aroma is slightly reminiscent of castor oil. This oil absorbs into the skin well, but it can be very heavy when used on its own. It is also a relatively unstable oil.
