Yes it can help with candida. Martha Christie cured herself of candida and chronic fatigue syndrome with urine. I've also found it helpful doing urine enemas, drinking and body rubs. Start with very small amounts, it can be very detoxifying.
I'd recommend doing some reading around the subject first particularly the following...
"The Golden Fountain" by Coen van der Kroon
"Your Own Perfect Medicine" by Martha Christie
"The Water of Life" by J.W. Armstrong.
Don't forget mercury toxicity can underlie chronic candida.
