I have been taking mms for nearly 3 years using lemon drops. But some 10 days ago this seem to be not working. Because one morning I got up with severe pain in my thigh. Hence here we have an ayurvedic medicine Mahasudarshan kada. I took three times a day. I was relived. I also pumped h2o2 in my mouth (bill munro). After 10 days I was relieved. I hope this was a Flue. I would highly appreciate if u can inumerat on the advantages of using HCL 4 persant, over lemon juice.
