How much is $25.00 us dollars in Bangkok?

Is it not very much or a lot or what , I am trying to help a person there and I don't know how much to send, He is a biochemist and healing people with swine flu, bird flu h1n1 whatever they are same thing, the guy is a genius but he is poor there and they have health care rationing, anyway we have the cure and it works in 5 hours if done rite, even in advanced stages where the lungs are full of fluid, fluid is removed with a digestive enzyme 90% of fluid gone in one day. I have not had the shot , I got the flu Friday morning and by midnight I was eating and feeling fine. But I don't know how much money to send him and don't want to ask him.
