Develop your skills as an herbalist to do what you love as a business!

This series offers a range of information in an intensive classroom format with approximately 90 hours of in class time plus an additional 50-90 hours of integrative at-home study homework (including detailed monographs, research, plant ID, seeing clients, custom formulation, final project/presentation). Gain and practice a range of skills to help you turn your love of herbalism into a career or to deepen your home practice. Students who complete the program will receive a certificate of completion.

The Advanced  series can be taken as a stand-alone program for students who already have a solid background in Western herbal medicine. Beginning students may take all of Maria's series together in one year (which is quite intense with a lot of homework!) or spread out the beginner Home Herbalist and Beyond Series for year 1 and then take the Advanced in year 2. You may also opt to take the Home Herbalist and Beyond Series as online classes at your own pace during my off season, then pick up the Advanced course in the spring.

This series is also a component of the Herbalist Intensive Training Program.

To complete the entire program and get your Herbalist Certificate,  you will need to attend the Home Herbalist Series, Beyond the Home Herbalist Series, and Advanced Series, and complete all accompanying homework for each series.

* The Advanced course is not currently available online. Stay tuned in 2020. I might design a hybrid course that incorporates online material with a consolidated set of live classes for students who have to travel great distances. Please email me at if this interests you.

Certificates of Completion for the Advanced Series will be granted to students who attend at least 11 of the 15 classes.

The Herbalist Certificate for the Herbalist Intensive Training Program will be granted to students who complete all three series and all accompanying homework.

Pros & Cons

It may seem odd to lay out the pros and cons of a course I teach... after all, shouldn't I think it's absolutely amazing and that there are no cons at all? Well, I do! But, I'm an editor by nature, and there are pros and cons to every single herbal study program across the country. If you're deciding whether or not to become an herbalist and where to study, you'll want to ask yourself what kind of program suits you and your needs best.


  1. Clinical, western herbalism focused topics
  2. An infusion of science and evidence-based medicine with clinical experience and traditional uses of herbs and a teeny touch of plant spirit medicine
  3. Covers a lot of material in a relatively short amount of time
  4. This series provides 90 classroom hours and up to 90 home study hours. Along with part of the other two series as part of the Herbalist Certificate Program, you'll have 300 hours towards the American Herbalist's Guild recommended 400 study hours plus 400 clinical hours.
  5. Relatively affordable, especially compared to multi-year programs
  6. Delves into all the major topics and skills you'll need to develop an herbal practice (especially when combined with the Home Herbalist and Beyond series)
  7. Diverse course materials include detailed and lengthy notes, audio recordings, homework assignments, and a few videos
  8. Classroom time will be a mix of (mainly) lecture and demonstration, with some hands-on activities, garden walks, and in-the-field identification and harvesting
  9. No matter what you do with this program, all the course material will always be available to you
  10. There is no deadline to complete homework assignments


  1. Herbalism is not in any way a regulated practice in the USA. It is not licensed, nor is there a nationally recognized certification for herbalism. Therefore, your certificate does not have any sort of legal standing, though it does still show what you have learned and completed. This is true for any herbal study program in the United States. For students who think a certificate is everything, this can be a bit of a buzz kill.
  2. Not accredited, which is not necessary in any way for herbal studies and your ability to practice as an herbalist. (Accreditation does allow for some benefits like student loans and veteran benefits, but otherwise, it's grossly more expensive for accredited schools compared to non-accredited schools for the exact same content.) Most herb schools in the nation are not accredited.
  3. Short and dense. Because this is an intensive program where we cover a lot of topics in a short amount of time, you'll spend a lot of time in the classroom with rapid-fire lecture time, plus a little bit of hands-on and in-the-field time spread throughout the day. Therefore, this is not in any way a leisurely or extremely experiential class. We will not be spending several hours per class out in the field sitting with the plants or harvesting them. We also will have limited in-class opportunities to work on clinical hours and observation. (Multi-year programs often have a heavy clinical component in the later years where working in a clinic setting is almost entirely what you do. Which is awesome, but also is a greater time, energy, and money commitment for you.) You'll need to develop these skills further on your own through gradual practice, mentorship, etc.
  4. Limited business training. Although we will cover some introductory topics like setting up a practice, intro to GMPs and labeling, and the regulations surrounding clinical practice and selling herbs, very few business skills are covered in this course such a bookkeeping, taxes, and marketing.
  5. Limited exposure to Ayurveda, traditional Chinese medicine, and plant spirit medicine.

How This Compares to Other Herb Schools

  1. The course content in each of my series is relatively comparable to most "one weekend a month" (for 5-8 months) style programs, although they tend to be more informative yet less experiential and different schools may have different styles/focus (for example, Ayurveda, TCM, plant spirit medicine).
  2. My series are also relatively comparable to most online study programs, though each school's program covers slightly different topics and has a different flavor.
  3. My series do not provide anywhere near the level of education and clinical exposure of multi-year study programs like the Vermont Center for Integrative Herbalism and Arbor Vitae in New York City... but they also take up less time, money, and in-class commitment for you. You only spend 30 hours each in the classroom for the Home Herbalist and Beyond Series, and 90 hours for the Advanced. In contrast, VCIH's Clinical Herbalist three-year program has 600 classroom hours. I can't possibly offer the same amount and level of material and experience in 1/6 the time.

Nonetheless, I do believe my herbal study series and program offer a fabulous opportunity to study herbal medicine and learn to become a practicing herbalist, especially for self-motivated students who enjoy a classroom learning environment and are looking for an economical and convenient way to study with high-quality information and materials.
