What are liniments that are safe for pregnant for back pain?

Red Liniment. J r watkins natural pain relieving red liniment with camphor and capsicum will sooth and get hot while helping the pain. Hope this helps, but you will not find safety info on natural products like fda products.
No trials. I don't believe there are any clinical trials on the use of these types of medications in pregnancies, so probably to be on the safe side i would recommend avoiding them. If you have back pain, heating pad and massage are two very good options.
