Take my advice and don’t ingest apple cider vinegar. I read up on it and it is supposedly one of the best things you can use as a natural healer. The only problem is it tastes like donkey sweat (I’m assuming here) and it burns going down. I tried a little this morning and three hours later I still want to throw up. Topically, It works great on dry scalps and other ailments, but I am convinced this substance should never be ingested, despite what well meaning old people might tell you.
