After taking it for a month, my burning pain was pretty much gone. I took for another month just to make sure. But it did not get rid of my mouth burning (my burning sensation usually occurs on different parts of the body depending on the hour and mouth burning sensation was everyday). I went back to the herbalist and he gave me a different concoction of the herbs for the mouth burn. I have been on it for the past week and the burning sensation reduced by 80%. The verdict is whether the pain will come back after I stop taking it.
I would recommend that you try it. But make sure you go to a reputable one. Don’t get a full month worth of the herbs, just buy 5 to 7 days worth to try and see if you notice improvement. My herbalist said you should start to see improvement and if not, he needs to tweak the concoction (he didn’t need to in my case). The herbs were expensive but was worth it. I recommend brewing the herbs yourself (vs. buying it packaged).
No side effects for me except the tea tastes terrible. But it was worth it.
