Hi @bollutech, Below is my review on this app:

Pros:

i. This is probably the most detailed app on this topic/category
ii. Despite having plethora of info, this app is for FREE
iii. The app guides about the dosage and combinations

Cons:

i. While browsing through a topic, users has to go back to the main page to browse through the different sections of the same topic. Such navigation makes the user experience bad
ii. App requires one time registration with some necessary details

Below is my rating for this app:
