I have used corn silk extract for UTIs with great success. I found that cranberry works specifically on a particular bacteria associated with UTIs, but if it doesn't work for you, what to do?
This is the one I used: https://www.herb-pharm.com/products/corn-silk
I found immediate relief from pain/itching - by the end of the day, that symptom was gone.
The dosing is easy - 1 dropperful in a water dilution / dose (there are instructions on the label for dosing)
You may find this option works faster & costs less than all the cranberry remedies.
Corn silk works wonders for my dog's incontinence. He was suddenly dripping and peeing in his sleep even though he has never peed in the house in his life. I see that most of the posts have been about female dogs and their spay incontinence but I just want to say that corn silk capsules eradicated my adult male dog's incontinence by 99%.
He is a 70lb dog and I give him one capsule per meal twice a day. I also time when he gets water but not reduce the total amount of water given to him. This way he would not have to hold for as long. In two weeks he went from dripping in his sleep every day to needing to go out earlier than his potty breaks. We listened to him when he would indicate wanting to go and slowly his schedule was back to normal. It has been a month and a half and he stopped having incontinence completely. I will likely give him cornsilk long term since it is inexpensive and effective as incontinence prevention.
Corn Silk Tea: Since I did not see this as a remedy, I thought I would post. A friend recently had some bladder pain and she went through 2 rounds of antibiotics with no success. She tried other holistic remedies, but in the end her mother boiled the silk from the outside of corn into a tea and that did it for her. I don't have a recipe, but if you search on "corn husk tea medicinal" you will find it.
Having suffered from cystitis many times over the years, I always have handy some Cornsilk, and it has always worked for me. It is natural and cheap from a good Health shop. It is alkaline. You place a small quantity in a jug and pour on boiling water and leave it to cool. Best to leave it overnight, but if desperate, you can drink some after about 20 minutes. I also drink plenty of water afterwards.
I once had cystitis for 9 months when I had tried just about everything, but this was my first real relief. You can buy it from a good health shop and it is cheap. It is the dried ears around corn. God has given us everything we need in His creation.
I tried to do the vinegar douche but I got worst I started getting pain in the vagina, thank God for corn silk and shave grass tea I felt better 3 hours later. They usually sell this in the mexican stores: One bag of corn silk and boil it in 4 cups of water, and for the shave grass tea they sale those in tea bags so you put that in a cup of hot water and drink it drink as many as many cups as you can, keep drinking it for 5 days or longer, even if you feel better. Both teas work but if you only find the corn silk it will work fine.
