Does anyone here still use bitters as medicine? Which ones do you use and for what ailments? Bitters are known to have medicinal qualities.

I've never used them beyond making killer cocktails... But, I've noticed that orange bitters, in particular, will imbue me with an added vigor or gusto, at times. I've heard certain bitters can be consumed for stomach and headaches but, I've never been able to replicate the affect.

What added physiological or psychological sensations have any of you noticed when consuming bitters? Which bitters have you consumed for what particular ailment(s)?
I usually use either Jägdbitters (a Jägermeister-like bitters sold at Aldi) or my family's version of Bärenjäger (which I prepare at home - nope, it's not bitters, but it was also used historicaly for the same purpose), mostly when I feel a cold coming up due to catching rain.

Jägermeister gives a soothing feel to the throat if taken when you're already with the cought, but if taken as a preventive, it makes me feel like a warm blanket was dropped over my shoulders and I don't get the actual cold afterwards. It always works we me too, better than pharmacy bought stuff.
