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

I think Tiger Balm is safe for application during pregnancy but I think it is not very effective for relieving backaches. As for Salonpas, it is best to check with your doctor, as it is not supposed to be used during the last three months of pregnancy. You can consider trying other ways of relieving backaches such as prenatal yoga, swimming, and buying body pillows for better support during sleep.
