|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!
Here are some studies if you want to read more!
