There are several threads on this Candida Forum (not the Dr. Jeff forum, which tries to play down posts about gymnema) citing a study in which the herb called gymnema blocks the switch that candida takes to turn into hyphal growth.
It is a shame that the Dr. Jeff ("the candida expert") forum has removed my ability to post on his forum after I made a post there about gymnema. Gymnema does the same thing that the product that Dr. Jeff sells does.
I guess Dr. Jeff didn't want people to have a less expensive product, that he doesn't sell.
To find the threads in this Candida Forum about gymnema, simply go to the search box at the top right of the screen within this forum and type the word in.
