local health food store or pharmacy.
we used gentian violet the first time we had thrush and it worked well.
the second time, i did not have relief from pain for over 5 days so i switched to using citricidal grapefruit seed extract diluted in distilled water (10 drops GSE to 1 oz of water). my pain and symptoms went away in less than 2 days, but i continued using the GSE for another 3-4 days.
i have heard that different things work better for different people, so if the gentian violet does not provide relief for you and baby within a week, consider trying the GSE or vice versa.www.drjaygordon.com
