Thanks for posting this! I just happened to realize that licorice might be very important for PD because it impacts cortisol levels in our body and these seem important for PD in a number of ways. See the discussion on this post for more details on this: http://www.parkinsons.org.uk/forum/thread/52270
May I ask you if you feel any noticeable impact on your pd symptoms when drinking this licorice tea? Also, can you pls clarify if you buy the tea already made (the twigs already macerated) or if you buy the licorice in natural form and macerate it yourself?
