You can use boric acid to apply to affected areas of yeast in your groin area. I buy the boric acid and let some coconut oil melt, mix equal parts of coconut oil and boric acid, pat it down in a covered container and store it in the fridge. It will soften at room temp, and you can massage it in your hands and apply to the affected area. You can do this up till a month every day.
Just don't eat any grains, flours, any kind of sweetener whatsoever, which I've found almost impossible on a low income, but I don't know your situation. Always filtered water, because the chlorine kills everything good and bad in your gut.
You can bump up your mag to 400-500 2-3x/day. We are all deficient past the age of 30, and it's now processed out of everything.
You can bump up your probiotics, and be sure to get one that is shipped cold. That other stuff just doesn't work.
Making homemade yogurt from an organic milk would help you tremendously. I'm vegan, but darn, this helps so much. THE BEST thing you can put into your body would be home made yogurt, from organic milk, and new batch made every few days. It doesn't keep long. Yogurt makers are relatively cheap these days, too. Ebay, Amazon, they all have them. We have an organic farm just miles from here that I'm going to hit asap! You can also make home made yogurt in a crockpot.
A normal eco environment is necessary for the production of B vitamins, so you should supplement your diet with a good quality B Complex, not a One a day, a complex, and go by weight. If you're a 100kg, you should take the B-100's.
Those teas are okay, and Black-Walnut , okay, never worked for me. The only thing that helps me now is the probiotics, filtered water, boric acid, and less bread, flour, I only eat gluten free oat flour, and just less of all of the bad stuff. Used to be easier but Candida has mutated. Diflucan doesn't do any good as towards a cure. Nothing, nada....
NO DIET DRINKS, NO COKES, NO ALCOHOL......once you get it, it will rule your life. the only reason I'm alive is that I don't eat Sugar a lot, and drink water, and take probiotics, and just do the vegan thing. Unless you're eating organically grown free range meat, don't eat meat...it has steroids, Antibiotics , and hormones injected into it. I used to know a vet who would say he had a thousand head to inject, and I would say with what, and that's what he told me. Then, I researched it myself.
Don't smoke. Anything. Just don't. Avoid stress. You have catecholamine dumping when you're stressed and this in turn, sets up your body to release cortisol, which wreaks havoc and promotes yeast growth. Do not take Steroids or Antibiotics unless it's an emergency.
For stress, you can get some B5, or it's also called, pantothenic acid. Look it up. I'm ordering CBD oil so I can calm down. If I get stressed, I can feel the Candida preparing to wage war! No lie, the truth, you become that labile with this curse.
