I won't bash on about the other health benefits of bicarb (though there are many) I will let you google that for yourself!
You can get premium grade bi carb from the chemist, but the stuff from the supermarket is the same , just lower grade. And its cheap!! I get mine from Boots, a tub for a quid. As bi carb is alkaline it balances the bodys natural PH, especially with all the acidic products we allow into our bodies, and gives us what we need. (again look into this for yourself).
Basically I mixed a teaspoon of bicarb with a smidge of water and made into a paste. I then used some savlon antiseptic cream (smidge on your finger to pick up/carry the bicarb paste) and pasted it/rubbed into the area.
This I did four times a day.
I also ingested a teaspoon of bi carb ( mixed with warm water) three times a day.
Within 24 hours it had shrunk. Within 72 it had all but gone!
A cyst is acid. Bi carb is alkaline. Dig??
I'm guessing apple cider vinegar works in the same way a lemon does on the body. Its acid but the body turns it to alkaline.
I hope this helps!
