As Mercury is debilitated you shouldot be wearing Panna or Emerald, despite it being the stone for Mercury. As Mercury is Neech, you need to remove its Neechta and the same you can do by way of charity and mantra. Through Gems therapy you are absorbing the Mercury rays into your body which will only strenthen its Neechta. You need to remove its Neechta and to remove it by donating it and not taking it further in your body. You should do the Bhudh mantra as given earlier atleast 1 mala daily. The more the better. You should not consume Sabut Mung on wednesday rather make a offering to a needy person or in a temple. Dont wear Mercurys colour on wednesday that is Green.
I hope you followed what I am suggesting that because Mercury is Neech you have to remove it and not absorb in your body.
