I searched through the posts but could not find any post on the use of Belladonna for treating PD. Belladonna Tincture is used to treat the rigidity, tremor, excessive salivation, and sweating caused by Parkinson's disease. It was the main treatment in 40's and 50's before discovery of Ldopa. This is evident from literature of those times. One of such paper is given in the below link which end with following conclusion (keep in mind that this was published in 1948):
"Symptomatic treatment of postencephalitic Parkinsonism with Bulgarian belladonna root extract is superior to all other medications tried in the past."

Normally its tincture with strength of 1:10 is use
I was wondering whether someone on this forum has ever tried it?
