I have seen this same subject mentioned so many times when reading info at Earthclinic.com. Do a search function at this site. www.earthclinic.com/ I have been using remedies for years from this site for years for me and/or pets. So far everything has worked and we are still alive. You have to do a bit of reading and use common since before trying some of the remedies. Some of the remedies have been around and used for hundreds of years before Big pharma started trying to put copyrights on everything. Most of their stuff had their start from naturals anyway. Most anything you read from a contributor named Ted from Bangkok, Thailand. www.earthclinic.com/ about.php He has popular remedies all over the internet has a varied education background including biology, chemistry, biochemistry. He has some great remedies using common house hold & natural products. He is most known for his treatment for pets for red mange which was how I ended up at this site a few years ago. His remedy works when types don't or may harm your pet. Great site for researching for holistic & natural remedies with real life experiences posted both positive & negative results. It has saved me so many doctor or vet visits in the last few years.
