Rose hip

Rose hips from Rosa rugosa (beach rose)

The rose hip, also known as rose haw or rose hep, is the fruit of the rose plant, that typically is red-to-orange, but ranges from dark purple to black in some species. Rose hips begin to form after successful pollination of flowers in spring or early summer, and ripen in late summer through autumn.

Propagation

Roses are propagated from hips by removing the achenes that contain the seeds from the hypanthium (the outer coating) and sowing just beneath the surface of the soil. The seeds can take many months to germinate. Most species require chilling (stratification), with some such as Rosa canina only germinating after two winter chill periods have occurred.

Usage

Rose hips are used for herbal teas, jam, jelly, syrup, rose hip soup, beverages, pies, bread, wine, and marmalade. They can also be eaten raw, like a berry, if care is used to avoid the hairs inside the fruit.

A few rose species are sometimes grown for the ornamental value of their hips, such as Rosa moyesii, which has prominent large red bottle-shaped fruits.

Rose hips are commonly used as a herbal tea, often blended with hibiscus, and also as an oil. They can also be used to make jam, jelly, marmalade, and rose hip wine. Rose hip soup, "nyponsoppa", is especially popular in Sweden. Rhodomel, a type of mead, is made with rose hips.

Rose hips can be used to make palinka, a traditional Hungarian alcoholic beverage, popular in Hungary, Romania, and other countries sharing Austro-Hungarian history. Rose hips are also the central ingredient of cockta, the fruity-tasting national soft drink of Slovenia.

The fine hairs found inside rose hips are used as itching powder.[1] Dried rose hips are also sold for primitive crafts and home fragrance purposes.

Nutrients and phytochemicals

Rose hips are particularly high in vitamin C content, one of the richest plant sources available. However, RP-HPLC assays of fresh rose hips and several commercially available products revealed a wide range of L-ascorbic acid content, ranging from 0.03 to 1.3%.[2] Rose hips of some species, especially Rosa canina (dog rose) and R. majalis, have been used as a source of vitamin C. During World War II, the people of Britain were encouraged through letters to The Times newspaper, articles in the British Medical Journal, and pamphlets produced by Claire Loewenfeld, a dietitian working for Great Ormond Street Hospital for Sick Children, to gather wild-grown rose hips to make a vitamin C syrup for children. This advice arose because German submarines were sinking commercial ships, making it difficult to import citrus fruits.

Rose hips contain the carotenoids beta-carotene, lutein, zeaxanthin and lycopene, which are under basic research for a variety of potential biological roles, such as inhibiting oxidation of low density lipoprotein.[3][4]

A meta-analysis of human studies examining the potential for rose hip extracts to reduce arthritis pain concluded there was a small effect requiring further analysis of safety and efficacy in clinical trials.[5] It is not considered an appropriate treatment for knee osteoarthritis.[6]
