Technically, it doesn't have any activity against candida species. However, some chitin inhibitors are known to work synergistically with other antifungals. The candida cell wall is composed of Beta Glucan, Mannan, Ergosterol, and Chitin mostly. It is known by medicine candida increases chitin production when beta glucan or ergosterol are attacked. It means, Lufenuron may works well if you are taking an azole or a polyene such as Nystatin. It may works with some natural antifungals too. I think if you take it alone, it wont do anything. Try to combine it with some other antifungal substances. Independently of that, cleaning the colon with water and injecting an antifungal that reaches the cecum is the only way to eliminate the biggest part of the infection. According to many medical studies, candida growths more in the Ileum and Cecum than any other part inside the intestines.
