I absolutely recommend "Herbal Medicine: Natural Remedies" to everyone, except advanced herbalists and those who are very experienced and knowledgeable about different herbs, DIY recipes, and herbal remedies. For those people, this may be a bit too simplified. But for everyone else, this is really cool, fascinating stuff that is very correct in its information.
Crush a few fresh strawberries into a scrubbing pulp that you mix with a pinch of stain-removing baking soda and enough water to make a paste. Apply the mixture to a soft-bristled toothbrush and polish for a few minutes once every 3 or 4 months. (More often can erode tooth enamel.) The astringent malic acid in strawberries helps buff coffee and red-wine stains from teeth. (Here are 4 more foods that whiten teeth naturually.)
Mint has been used for hundreds of years as a health remedy. Peppermint oil might help with irritable bowel syndrome -- a long-term condition that can cause cramps, bloating, gas, diarrhea, and constipation -- and it may be good for headaches as well. More studies are needed to see how much it helps and why. People use the leaf for other conditions, too, but there’s very little evidence it helps with any of them.
