Rosehips and inflammation

The fruits (hips) of the dog rose, Rosa canina, have been recorded as being an effective remedy for numerous inflammatory disorders in a variety of folk medicine traditions. Examples include arthritis, gout, haemorrhoids and inflammation in the intestine. Certainly, many herbalists add rosehips to a prescription of other herbs for people with these conditions.

Rosa canina (rosehip)

Active constituents contained in rosehips include phenolic acids, proanthocyanidins, tannins, flavonoids, unsaturated and polyunsaturated fatty acids, phospholipids, minerals, galactolipids and carotenoids (Chrubasik, 2008).

Preparing rosehip tincture

Although numerous studies conclude that rosehip preparations can be more effective than some orthodox medications, it has not yet been decided which of the constituents in rosehips bring about this anti-inflammatory and pain relieving effect.

This is a common theme throughout herbal medicine, and is thought to be because several constituents contained in the whole plant are required to work together to achieve the effect, for example, one constituent improving the absorption of others. It is frequently found that isolating (and sometimes strengthening) the constituents presumed to be the important ones, can actually either reduce the therapeutic effect, or bring about side-effects - so this is why herbalists use the "real" plant rather than a chemically altered version. Indeed, this is also the reason why herbalists combine several herbs in a prescription - to increase effectiveness and offset any adverse effects.

Here are my gathered rosehips, tincturing, soon to be pressed and bottled - although I did have to decant some off yesterday for someone who just couldn't wait!
