Can you use tiger balm plaster or salon plas during pregnancy for the back ache?

According to its website, it is market to also be available to use during pregnancy. I've not used during pregnancy, although I did went for occssional pre-natal massage if the pain gets too unbearable. In any case, it's best to consult your gynae before you use it for precautions' sake. http://www.tigerbalm.com/us/pages/tb_product?product_id=3
