Its called Gentian violet -its an anti fungal.
Here are loads of articles on thrush on kelley mom
Some chemists stock gentian violet it but may have to order it or you can buy it online via ebay from Mistral labs. You only need few ml so buy the smallest bottle available. they only seem to have large amounts listed at the moment but probably 10ml would even be way too
much.
Here is the method I followed (I can't find the original link):
You need
gentian violet cotton 10ml is more than enough
Cotton buds
breast pads
Treating your baby:
When your baby is asleep after the last evening feed lay them down on their side (my son naturally sleeps like this you may have to wedge your baby with a rolled towel or something, with a terry square or muslin under their head to protect bedding if they dribble.
In your bathroom , over a sink, first wet the end of a cotton bud then dip in gentian violet-be careful with it, it stains.
Take the bud to your baby. Gently pull down their bottom lip and insert the bud into their mouth (not too far, just onto the tongue), they will suck the bud and distribute it around their mouth you can also give it a wiggle into their cheeks too to make sure its distributed. Your baby shouldn't wake up if done gently though they might pull a funny face.
To treat you:
Have some breast pads to hand and a bra to sleep in.. Dip a cotton bud in the GV and apply fairly liberally to the whole areola/nipple area. Put on your breast pads and go to sleep.
Before your next feed or some time over night get up and wipe away as much of the GV as you can, your skin will just be lightly stained , it is removed most easily with baby wipes though I used washable wipes solution and that worked fine. Then just wipe over your nipples with water just to get rid of the wetness from the baby wipes.
Do this for a max of 7 days in a row.
YOur baby will have a slightly purlple mouth but it fades in about 2days.
You may come across methods that say to treat you and then feed your baby to distribute the GV but you will both end up very messy. This method is easier than drops as it only needs doing once a day. Just be careful with GV as it does stain.
At the same time I recommend you take a lot of probiotics to help you get over it . I bought a probiotics tablet. called Now which has 8 billion live per capsule and You need to take 10-40 billion so a few capsules. you can back thisu p with live yoghurt. The probiotics help to sort your body out and make it too acidic for the thrush to survive.
we found the thrush nearly went completely with GV and then has died altogether in the following weeks.
Hope that helps
