Several years ago, my husband had an abcessed tooth. A filling had been broken out for some time and we did not have dental insurance. He went to a health food store and asked about a remedy for pain relief. The propietor highly recommended Alpha Lipoic Acid. My husband bought the 50mg caps, which were the least expensive. Back then, he weighed 230 pounds (6' tall). He took 2-50mg caps of Alpha Lipoic Acid every 4 hrs, 4 times daily, for 7 to 10 days, decreasing the dose after the pain was gone.
I can attest to this remedy also, because some time later, I had a toothache that would not quit. I treated myself with Alpha Lipoic Acid. It was kind of like a do-it-yourself root canal. My pain subsided each day and was totally gone within 3 days. I continued to take it a few more days. My tooth is still A-OK 10 years later. Did not require any dental work, even though I've been in for cleaning and x-rays several times since.
On a polar opposite note, I have been reading about Urotherapy - a little known frontier with claims of curing numerous aliments, including various cancers. Each of us have this readily available, tailor-made, built-in health dispenser at no cost. Research online, as it's limited experimental findings are under wraps among med books (has been for years). I did try it myself for a lower abdominal ache, after other natural remedies did not work over a 2 month period. I searched for a cure and found it. After 2 weeks of drinking a few ounces of 'mid stream in the morning', all pain was gone. Never had another symptom of who knows what. No, it doesn't taste bad. Think of it as intended - it's personalized medicine that won't harm you, but most likely will cure you. Do the research. I've found it tried, true and an essential entry in my emergency home care journal.
