Demetria was so helpful and answered questions so quickly, it was amazing.

Willa- 2020

I can’t believe how much I learned. I can’t understand how I lived my whole life without truly understanding the power of plants in healing. As a Nurse Practitioner I took this course to help understand and help my patients and I ended up opening a whole new world for myself.

I also loved all of the support and compassion in which this program was taught with.

Elisa- 2020

As a doctor I would never know how to answer my patient’s questions about herbs and herbal medicine.

I decided to take this course to be able to assist my clients, and I ended up learning a lot, and having so much fun. I got reconnected to nature and appreciating what the earth has to offer.

Demetria was attentive and patient with all of my questions, I appreciated that.

There’s so much to learn about old/new remedies from different cultures and beliefs. It was important for me to learn about the many different aspects of herbalism and botanical health.

You are a great teacher, and a wonderful person. I really enjoyed this course and all that I learned.

Salary Questions?

According to The base salary for Herbalist ranges from $47,656 to $71,210 with the average base salary of $57,696.  Phytotherapists offer more skills and services so their salary can be much higher.

According to the American Herbalist Guild:

The American Herbalist Guild cites a wider spectrum of salaries, potentially due to part time work. It says most herbalists make between $20,000 and $120,000 a year. This of course will depend on the herbalist’s business acumen, type of herbalism practices, where they are located, etc.. Most Clinical Herbalist charge between $60-120 an hour for consultations. Herbal product formulators can have potentially the largest salaries, as can herbal growers.

Any hidden fees?

We do not charge grading, mentoring, or certification fees. We do not supply students with any herbs, containers, or additional books. This course includes some additional books and supplies that we send, but we can only guarantee that students in the US can get supplies. We can’t make the same guarantee for international students, although we do still try.

Fees are clearly marked out. The course price is all-inclusive. Except for the transcript and certificate fee. Students can for free get a digital copy of the certificate. We found most of our students wanted a digital certificate to include in resumes, etc. This is the same for transcripts, a free copy can be sent digitally. Demetria does not offer personal health advice or consult with students.

Is there a time limit?

Yes, and no. We do not use words like lifetime access, which can be confusing and potentially misleading. In the course world it means the lifetime of the course, we want to be clearer than that.

We ask that students finish this course in 5 years depending on the program but if the student cannot they can ask for an extension. We realize life happens and we want you to be able to complete the program once you have bought it. We also want students to be able to integrate these practices into their lives. If your enrollment becomes inactive, after 1 year of inactivity, students will have to pay a reactivation fee. Contact Demetria for the fee amount.

Do you offer a certificate?

Yes, we do, only upon full completion of the course. Please know that if you do not pass you do not get certified, if you do not complete the work, you are not certified. Do not ask for special recognition of other work, these are specific programs, and we require complete of all of our work. In United States herbal and aromatherapy education and certification is school specific. No national standard or accreditation exists. Our programs have been taught to corporations, in colleges and universities and hospitals.

Students in the Phytotherapy program will get a certificate for each program they complete as they complete it, and then a final one at the end.

What about support?

We’ve got it.

Students can email, join our student support group, call or make an appointment to chat.

Do you have a supply list?

Yes, and no. You will find suggestions for supplies, herbs, and containers you may need in your classroom.
Here is the no part; your supplies are based on the projects and hands-on work you decide to do as part of your education.
We teach you how to formulate to decide what to make for your assignments. So if you are making a heal all salve we will teach you how to select the herbs and create the salve, each student has the freedom to use our recipes or create their own.
