The trade in the medicinal plants of southern Africa is a vibrant and growing industry. It is an important livelihood option for rural women, and for those involved, it is a major contributor to household incomes. It is valued at R2.9 billion annually in South Africa and at least 133 000 households in South Africa are dependent on this rich floral heritage.
According to Arnold et.al. (2002), the current number of medicinal plants of southern Africa used in traditional medicine includes 215 families, 1 240 genera, and 3 689 taxa (species, subspecies and varieties), representing 15% of the regional flora. Of these, 771 taxa are actively traded.
From a family herbalist point of view, having such a large number of muthi flora at our disposal is exciting. Very exciting! But it is also overwhelming. Somehow, one has to whittle the list down to a more manageable size.
In this top traded list, we narrow the number down to 125 plants. Enjoy!
Side note: The geographical region of southern Africa is defined by the area south of the Kunene, Okavango and Limpopo Rivers, and includes Namibia, Botswana, Swaziland, South Africa and Lesotho.

Criteria Used To Compile The Top Traded Medicinal Plant List
#1: Economic Importance
There are an estimated 200 000 traditional healers in South Africa and an estimated 80% of the population use their services.
It is no surprise then that trading in medicinal plants serves as a valuable source of income for several households in South Africa. According to Mander et al., the trade in herbal medicines in South Africa is estimated to generate an income valued at about R2.9 billion per year, representing about 5.6% of the National Health budget.
For example, in KwaZulu, Natal province, between 20 000 and 30 000 people (mostly woman), make a living from trading over 4 000 tonnes of medicinal plant materials valued at R60 million per year.
Dold and Cocks found that a total of 166 medicinal plant species estimated to be 525 tonnes and valued at about R27 million are traded in the Eastern Cape province annually.
In the Limpopo province, research by Botha et al. showed that 70 plant species were traded in Sibasa and Thohoyandou in Vhembe district, Giyani, and Malamulele in Mopani district. Moeng found that each medicinal plant trader in the Limpopo province generated more than R5 000 per month.
Williams et.al. did a semiquantitative survey of 50 umuthi shops on the Witwatersrand and compiled a lexicon of 511 plants traded commercially.
For the purposes of this list, we started with 15 taxa used by Western Herbal Medicine and Big Pharma. Next, we amalgamated the top 25 plants traded at the various muthi markets and muthi shops in southern Africa (as cited by the References used) into a master list of 108 taxa. The final result is 125 taxa that are of significant economic and medicinal importance.
#2: The Threatened Species (Red Data) List
It’s worth noting that in 86% of the plants harvested, the harvesting will result in the death of the entire plant. This has significant implications for the sustainability of supply.
Many of the traded plants are therefore under severe pressure in the wild and have been added to the Red Data List. If you are from southern Africa – whether you like it or not – you are a custodian of this floral heritage and you have a responsibility to protect and preserve it.
Correlating the traded species list with the Red Data list resulted in a list of 86 threatened species that are actively traded. Of these, 25 appear on the Top Traded list (see the Red List), and 61 taxa do not appear on the top 25 traded list. We’ve compiled the latter into an Orange List (see below).
Categories of Traded Medicinal Plants of southern Africa
Using the above criteria we painstakingly combed the literature (see References), and narrowed the list of 771 taxa being traded down to 125 species from 63 families. Now that’s a little more manageable!
We’ve divided the taxa into four categories.
- Green List: Medicinal Plants used in Western Herbalism and by Big Pharma
- Red List: Threatened Top Traded Medicinal Plants
- Blue List: Top Traded Medicinal Plants (Not Threatened)
- Orange List: Threatened Traded Medicinal Plants (Not in Top 25 traded)

The Red List
Threatened Top Traded Medicinal Plants of southern Africa

I am so excited that this course looks so closely at South Africa’s herbs and not just the overseas ones 🙂
what an information, it is making me a bit anxious and wondering will i know all this herbs , but ooh yes with determination, yes i will know.
We take south Africa for granted and never realized there is so much healing and for me herbs that I used by traditional healers, i never knew its herbs that one can know.
taking this course, it is really a mind blower and looking forward to building a career.
Our country is rich with herbs, it is very sad that some of them are on the endangered list.
This is very interesting and eye opening information.
Sjoe, this was very interesting. Thank you.
Wow!! Very usefull info. Did not know SA have so many medicinal plants. Sad that so many plant are endangered.
Thank you for all the information. It is very sad to have so many of our plants on the endangered list. I will have to work very hard to become familiar with all the plants and their benefits.
This was the most amazing information that I have received in a long time.
Wow!! So many herbs and families, never realized so many are on the endangered list. I definitely need to find out what can be done for herbs in my area. Thanks for the information, this will definitely take some time.
wow pick 3 that’s impossible every plant has something that stands out and researching each one and their benefits will take time. and while my attention is strictly on the medicinal use I can’t help but to want to start looking into the plants on the red list to see what can be done to save them.
Thank you for all the info. Now I can work through the list and familiarise my self with each plant. Onle love
I was very surprised at the size of the herbalism market in South Africa and am looking forward to becoming a part of this community. Having said that, I found the list of medicinal plants in South Africa overwhelming and am going to have to work really hard to become familiar with all of the different plants. It is also concerning that so many plants are on the red list.
Spoken like a true family herbalist Kerry. 🙂
