Thank you for your contribution the the fava bean users for PD. I have been using fava beans and the extracts of l-dopa from the plants and beans I grow myself since 2009. I have never had side effects from them. My PD symptoms are controlled and I still am learning to do new things since introducing them to my life. Still learning to play new instruments , garden organically, dance, sing etc and live a very full, extremely busy life. I encourage anyone who is able to use favas and especially, to grow them. Get sunshine, exercise and eat good organic food. Try to live stress free and love those around you. Enjoy each moment and try to enrich the lives you touch. God Bless you my family with PD. Love Aunt Bean
