Just a quick update.... found out this last week that the fava pod tincture (cutting up undried green fava bean pods tiney and placing them in brandy and shaking it for a month works even better than the top bud tincture for PD control) I got tired of waiting to find a chemist to test a few tinctures from last year and tried this one. One drawback was that if taken before bed...I do not sleep, my energy level is too high, whereas the top bud tincture relaxes me in small doses. I have needed less of it and took it as little as once in 24 hours to be symptom free. Of course I am stilll eating egg plant and sweet peppers( which are conming in well in the garden right now and I am freezing and drying them for winter) so it still could be a combination effect...but it works for me!
