Garlic is tough to chew and swallow fresh, and has been researched and the consensus seems to be you need to eat it raw. I love it cooked, but raw... yikes. I chew it a few times then choke it down with water, but I always have to put something in my stomach first then chase it with something else. I'm suprised how many people overlook Vitamin C. Vitamin C has been shown to have very strong health effects in Very High Doses. I supplement heavily, even more when sick. I have never had a problem taking vitamin c (when I take powder I mix with water and again make sure something else is in the stomach) except for really high doses of powder on an empty stomach. Search the net for Vitamin C, Read what Dr. Klenner did with it, read what Dr. Saul (pHD) recommends. Before the advent of all these drugs on the market that seem to cause side effects as bad as the disease or worse, Vitamin C was used Theraputically. I have also found that pure Whey Protein (which supposedly triggers the body to produce more Gluthitione - amino acid precursors) seems to help me feel better. Unfortunately there are no "Quick Fixes", but many of the previously mentioned herbs and Vitamin C can go a long ways to giving your immune system the Boost it needs. The NIH has funded a recent study about Echinachea has not shown much benefit. However I don't always believe these studies because I don't trust the motives or money behind them. Stats can say anything the money behind them wants them too. I would read about New Chapter Vitamins and Garden of Life supplements and Probiotics. A strong healthy intestinal tract seems to be the answer to keeping most disease at bay. And while you may or may not choose to use any of the products from these vitamin companies, you will open your eyes to many natural remedies and herbs you may not already know about.
