Pharmacy or shopping center to buy organic product :green clay green clay

[voyageuse]

Hello,

 

My friend just got a dire cut on his face (12 stitches , the cut was very deep ,12 cms long).

I visited a few forums about the green clay which is very effective for the healing of a wound and helps to avoid scars .

I couln't find on the web where to buy this green clay in Bangkok .If anybody can give me any help (which is quite urgent actually) shopping center,pharmacy adresses or organic shops in Bangkok you are all welcome.

Thank you in advance for your help.
