That's great to see people like you making efforts to eliminate problems like candida;
Just a word of caution though: be sure you cover all necessary safety precautions before you ingest something that is relatively unknown. This could be all a major breakthrough but it should be very carefully monitored.
Some things to consider are: whats the composition of this frogs milk? Could it be bacterial or even virulent? Whats the active compound giving its ability to kill yeast? Is there anything in that excretion that is harmful to human body? (It can kill the yeast but its side effects could be worse). Are there any unwanted interactions of the milk with substances that make up the human body (water, protein, lipids, minerals etc). Its frustrating that there are a lot of areas to cover in order to give you a good confidence level, and specially when one has limited tools to test it. I'm a chemist by trade but I don't have the tools to help you with your next move; I just wanted to let you know of some precautions in case you weren't aware.
