Under The Microscope: Rose Petals

Nowadays roses are mostly used for Bachelorette ceremonies and hipster lattes, but once upon a time roses, and their fruit, rose hips, were widely used as medicines.
Diarrhodon is the name given to herbal treatments containing roses, and there are lots of them, said to treat everything from liver problems to heart problems to digestion issues. Traditional Chinese medicine made use of the China rose for regulating menstruation, pain relief, thyroid problems and diarrhea.
Did any of the rose-based traditional therapies work? Well, at least one could have. As rose-hips are quite high in vitamin C, they would likely have done wonders for sailors afflicted with scurvy.
Today we mostly keep our rose-based products for use in cosmetics, and a few specialty food products like rose hip jam, rose water or syrup that is common in many Indian desserts, or rose flavouring for ice cream, liquor or hipster lattes.
Even though the petals in these photos have been dried for more than 5 years, they still retain a fair amount of pollen, seen as yellow specs on their surface.
