If homeopathic Dr says to use rhus tox 6c what is the diff with rus tox 30 What does one take daily?

My homeopathic doctor gave me rus tox because I had pain in the muscles of my shoulders. He gave me one capsule per day (30 power) in the morning half an hour before breakfast, for 5 days. I was much better from the third day. Homeopathy is a much better medicine than the typical classic cures of usual doctors. I have been using homeopathy for the last 15 years. During this time I only took antibiotics once. Stella K. 25 Aug 2009
