Grapefruit, like other citrus fruits, is a great source of vitamin C which helps to alkalize your body. It does other things, too. It’s a great source of citrus bioflavonoids, if you know how to extract them. That’s exactly what Dr. Bernard Jensen tells you in his book “Foods That Heal,” and I’m going to pass it on here. Vitamin C and the bioflavonoids strengthen capillaries and veins. Capillaries are those tiny blood vessels that run throughout your body and when fragile, can break or allow blood to seep out and form under the skin. So you have these blood spots most visible on your hands and arms. I had a particularly severe one on my index finger, covering the top of the finger from the knuckle to the first joint. It was nearly black, indicating a lot of blood. After a week, it wasn’t improving so I tried Dr. Jensen’s recipe for citrus bioflavonoids; handy because I had just pared and sectioned a nice grapefruit. Basically, take the grapefruit peel, cover with water, bring to a boil, simmer for 20 minutes. Strain and drink (just a little bit every day). I had to sweeten the juice with agave nectar. After the first day of taking it, the blood was noticeably lighter in color. By the second that third days, the blood was nearly half gone. Improvement continued daily until normal skin was all that showed. I’m not sure what part the grapefruit peel played in the blood being reabsorbed, but I am sure that it stopped the blood from continuing to seep into my finger.
