My husband is 80 years and has been suffering from PD for the past 15 years. Lately he started hallucinating and I didn't know how to handle the situation. He cannot sleep and tried to find and catch the imaginary people who he thinks are real. he was taken Entacapone with Levodopa, Carbidopa, and Pramipexole and started physical therapy to strengthen muscles. nothing was really working to help his condition.I took him off the Siferol [with the doctor’s knowledge] and started him on parkinson’s herbal formula i ordered from Health Herbal Clinic, his symptoms totally declined over a 5 weeks use of the Parkinsons disease natural herbal formula.i read reviews from other previous patients who used the herbal formula, my husband is now active, he can now go about daily exercise!! his symptoms so much reduced that now I hardly notice them.
