I am sorry, I wasn’t clear.
Apparently tap water has germs in it, so should be boiled (and cooled!) before using in a neti pot.
Since one already has to boil the water, one can make the neti pot water into tea at the same time as boiling the water.
Nope, I understood. I still wonder if the tea leaves might carry stuff that you wouldn’t want to introduce to your brain. But, I may make my tea different than you. I get my water hot and then put the tea in, but I don’t continue to heat after the tea is added.
