Tincture is like a brew - it is leaf distilled in vodka (preferable base) - or something else can be used, but for the amount you take I didn't consider it a problem.

You then start with say 2 drops twice a day in a bit of warm water - so you dont have to drink cup loads of tea or keep buying tablets.

My practitioner charged $15 for 50ml - I took it for 2 weeks, bought another bottle and only needed one more dose LOL.

HTH
