TIME TO HARVEST ROSE HIPS. Rose hips have been used since the stone age. They are high in vitamin C. Just one tablespoon of the rose hip pulp satisfies the daily need of vitamin C for one adult. Drinking rose hip tea supports the immune system. The tea also benefits the skin. The high vitamin A content commonly referred to as the "skin vitamin" helps to regenerate skin cells. It also helps with the elasticity of the skin and prevents wrinkles. Its astringent properties help to rehydrate the skin. I went out this morning to harvest a batch and now some are sun dried for tea and I also sun infuse rose hips in oil for a skin regenerating serum, salve and soap.
