To everyone wondering about how to use Black Walnut. I am a mother of 5 and have had some dental problems not only with my own teeth but my husband and children as well. There are so many reasons to use Black Walnut tincture for your all around health but I will only adress its tooth repair qualities here. First adults should start out by adding two droppers full to aprox. 4 tablespoons of water (enough to swish in your mouth) and swish in your mouth for at least one minute after brushing. Do not spit the solution out, swallow it because it not only works externally but mainly internally. Do this three times a day for at least two weeks, or until you see some benefits. Then I recommened taking a dropper full once a day or so to maintain a healthy balance.
All of our cavities were completely healed including my husband's wisdom tooth that was black and cracked in half. It will not grow new teeth but it will stop new decay and heal the cavities.
Remember that good health starts with a good attitude and healthy diet. Read Nourishing Traditions it is an eye opener!
