So Many Things!

I loved the down-to-earth, non-judgmental, Mom to Mom feeling of this program! I really enjoyed all the lectures and videos. I am a visual learner.

I loved the 9 books, they are beautiful. I also felt all the assignments on making herbal products were fantastic and guaranteed hands-on learning.

Amanda M.

Support! I had it.

Support, with this program I had it. I couldn’t believe the amazing things other students were doing with their education. It was so inspiring.

The courses have so much information and content. I couldn’t believe how much I learned. I can formulate professional herbal remedies for clients and support them.



This experience was truly such an inspiration. The things I loved most about the course were the wide range of references and visuals that were used as a collective curriculum. It is important as an educator to be able to have different types of references such as articles, audio clips, visual aids, cheat sheets, etc. to ensure that your information is being received effectively. I am so grateful for this opportunity.
