Rosehip

Rosehip - or wild rose, cenbreur (in Quebec), ass-scraper - possesses recognized culinary, medicinal and cosmetic virtues. Indeed, its cynorrhodon (a word that means the red receptacle containing the fruits of the rose and rosehip) is edible and is considered a food of survival by native peoples.
From a medical point of view, the rosehip berry (slightly acidulous) would be 20 times richer in vitamin C than the orange. It also contains vitamin B, vitamin PP, provitamin A and mineral salts.
This plant of choice to start a cure at the beginning of winter has often been used to fight against influenza (in particular), but also infections.
Moreover, used as a tonic and reinforcement of the immune defences, the cynorrhodon has medicinal properties known to fight against asthenia.
In China, berries of various varieties are used to treat chronic diarrhea and urinary problems.
In Denmark, scientists have shown that rosehip berry has virtues that can also alleviate osteoarthritis.
In the form of an infusion, rosehip flower petals are used to relieve headaches and treat dizziness.
