HEALING DIABETES WITH HERBAL TEA: EXPLORING THE ANTI-DIABETIC PROPERTIES OF TERPENES AND FLAVINOIDS IN THREE SOUTH AFRICAN PLANTS

Healing diabetes with herbal tea is not so unusual because next to water, tea is the most consumed non-alcoholic beverage. Therefore healing diabetes with herbs is fast becoming a popular modern day solution for this ever challenging health condition.

There are three main types of diabetes. All three types involve the production and secretion of the hormone known as insulin, produced in the pancreas. Insulin is the essential hormone that converts glucose into energy. It is responsible for the biological function of metabolism concerned with energy expenditure in the body.

Type 1 diabetes is where an auto-immune process has destroyed the insulin-producing islet cells in the pancreas. Type 2-diabetes is the most common version and develops over time. The body gradually becomes unable to use insulin properly, or doesn’t produce enough insulin. Third is gestational diabetes, which occurs during pregnancy due to hormonal changes, genetics and lifestyle.


People who suffer from diabetes constantly have high blood sugar and cannot produce enough insulin

Diabetes is a critical condition and statistics reveal that over 400 million South Africans are affected and thousands go undiagnosed. [1] Further, it is estimated that another 5 million South Africans have pre-diabetes. This is when blood sugar is higher than normal but not high enough to be diagnosed as type-2-diabetes. Of greater concern is the alarming statistics in the development of the chronic complications of diabetes. Kidney failure, heart attacks, strokes, lower leg amputations and blindness are some of the symptoms of this devastating disease. [2] 

Diabetes is a slow-onset condition and early detection is of paramount importance

Healing diabetes involves the recognition of the onset of the disease and to determine the best mode of treatment. This disease is generally believed to be incurable; and the pharmaceutical drugs available are not affordable to the poor. There are several means of managing and treating diabetes, however, natural remedies are proving more effective. This is because unlike synthetic drugs and oral medications healing diabetes with herbs does not cause undesirable side effects.

Extreme eating and lazy lifestyles are the main accomplices to the development of diabetes. Of course some people are genetically pre-disposed but this disease is predominantly preventable. And it is possible to still have a healthy quality of life by healing diabetes with herbal teas.

People have become urbanized and no longer care for healthy food but instead invest in processed takeaways. It is known that high sugar diets can lead to obesity and diabetes and we are seeing this everywhere today. To truly cure diabetes we must first control the corporate marketing of unhealthy foods in our own minds. Then we must put in place proper health systems that provide standard preventative and curative care for affected individuals.

Healing diabetes with herbs will provide new therapies with less side-effects 

Safe curative treatments for diabetes are yet to be developed although traditional healers still practice herbalism for the treatment of diabetes. People diagnosed with diabetes need the best possible treatment available and this includes patient education. As diabetes continues to increase, so does the need to create awareness and strategize how to reduce the risk of diabetes.

The world’s diabetic population is diverse and we need herbal healing for individual treatment plans. When the pancreas starts showing signs that it can no longer produce enough insulin we must immediately start considering herbal remedies. By healing diabetes with herbal remedies we can access safer, cheaper and more effective treatments.

Healing diabetes with herbs will not interfere with synthetic drugs like insulin 

Herbs can be used as an anti-diabetic remedy alone, but can also be used safely with other drugs like insulin. In fact most anti-diabetic herbs will also alleviate the awful side-effects of some diabetic drugs. Nausea, vomiting, dizziness, anxiety, swelling and headaches are some examples. Likewise the resurgence of herbal medicines has led to increasing concerns over their safety, quality and efficacy. This is an important medical development because it led to human clinical trials and published research papers that prove the safety of herbal medicine.

Which plants can be used to heal diabetes? 

In nature we are blessed with at least 389 medicinal herbs that have been identified and proven to treat diabetes. [3] However, it has been reported that more than 1200 traditional plants may have been used traditionally to treat blood sugar. [4] These plants are recognized to contain valuable medical properties to treat both high and low blood sugar. There is even a plant named “the insulin plant” that originates from India. [5] As custodians of herbal healing traditional healers may hold the key to unlock many diabetic complications.

In this article we will analyze the top three herbs used for traditional healing of diabetes in South Africa. Let’s start with the national flower of the country.

P1 Sugarbush (Protea repens) 

South African’s enjoy 1700 species of Protea plants but most people feel that all Protea flowers are equally our national flower! Protea Sugarbush or “Suikerbossie” as it is known in South Africa occurs mainly around Cape Town where the fynbos biome grows.


The Sugarbush has been exploited for centuries for the nectar produced by the flowers. This abundantly produced nectar was collected in the past to be boiled into sugary syrup, so-called bossiestroop, meaning ‘bush syrup’. This traditional medicine was used to treat chest conditions and as a component of cough mixtures. It was also used traditionally to treat diabetes. This remedy became an essential component of folk medicine chests in the Cape. The First Nations of the Cape of Good Hope taught their colonialists the secrets of the honey-pot of the Protea plant. [6] 

The Khoi-Khoi people teach traditional healers to heal diabetes by making a tea from the leaves of the Sugarbush plant. This is how we still do it today, although many healers now use capsules to administer the crushed leaves. Besides anti-diabetic properties this plant also has wound healing and blood cleansing properties that also aid in the healing of diabetes.


P2 Sutherlandia frutescens (L.) R. Br. (Fabacea), Cancer bush, Kankerbossie [7]

Sutherlandia is another Western Cape medicinal plant traditionally used to treat diabetes. This plant has been shown to have anti-diabetic properties in animal studies. [8] This study investigated Sutherlandia in preventing insulin resistance in human liver cell cultures and to identify genes regulated by this plant


We must understand that insulin resistance is a precursor to type-2-diabetes and is considered a serious condition

The results prove that healing diabetes with herbs can prevent insulin resistance in liver cells.

This study also revealed that Sutherlandia can alter human gene expression and points towards the mechanisms of the plants’ anti-diabetic actions. Healing diabetes by drinking ‘kankerbossie’ tea has been helping people overcome their condition for thousands of years. [9] Diabetics who use the leaves as tea report a drop in blood glucose levels and Sutherlandia has no signs of toxicity or side-effects. [10]


Sutherlandia can cure diabetes and cancer 

Aptly nicknamed ‘The Cancer Bush’ this herb displays anticancer activities and this supports the claims of South African Traditional Healers. The reason why Sutherlandia cures cancer is because it possesses apoptotic properties, meaning it can destroy any mutant cells. [11] Another reason is that Sutherlandia is loaded with antioxidants that are known to destroy free-radicals that cause cancer. People should be competing to use herbs to rid their bodies of free-radicals to beat cellular-oxidation and cancer.

Chemicals like terpenes, terpenoids and flavonoids have been identified as being responsible for the health benefits of Sutherlandia. Terpenes are the chemicals that give plants their fragrance but they also have their own unique healing abilities. These chemicals play role in the bioactivity of Sutherlandia and the anti-diabetic and anticancer properties of this plant are well established. [12] It’s amazing to know that we can literally heal diabetes and cancer by simply sipping on some tea!

P3 Cannabis sativa (dagga)

How does Cannabis control our blood sugar?

Dagga is already a household name for healing hundreds of medical conditions and diabetes is no exception. In fact Cannabis is now known for healing 700 known medical conditions.

Here is the link as a reference of this fact and you will notice how many auto-immune conditions are on this list. These type of diseases only really started surfacing in society after CBD (Cannabidiol) was removed from the worlds food-chain in the 1930's. In my opinion this was the very reason for the sudden appearance of an overwhelming count of cancers and auto-immune conditions. This is proof of Endocannabinoid deficiency and people need Cannabis to supplement the ECS. 


It is becoming more and more obvious that our hormones play a crucial role in the way our bodies uptake and regulate energy. The importance of this is that Cannabis and the ECS regulate the functions of our hormone system. Cannabis regulates blood sugar levels, by controlling the secretion and release of hormones like insulin and Melanin Concentrating Hormone (MCH). Scientists now know that MCH plays a role in the growth of insulin-producing beta cells of the pancreas, and the secretion of insulin. When MCH induces appetite it also increases insulin secretion from the beta cells and enhances the growth of the beta cells.

 Our sleep hormones also regulate our blood sugar

Melatonin is the hormone usually associated with our sleep waking patterns. Research proves that it also has a specific function in the control of insulin secretion from the islets of the pancreas. [13] This proves that melatonin has a distinct and detailed effect on insulin secretion. This is based on the biological fact that the pancreatic beta cells all have melatonin receptors. It is well known that sleep disorders and shift-working, are closely associated with reduced glucose tolerance and type 2-diabetes. [14]

Twenty years ago scientists had no idea of the functional importance of hormones like melatonin. Through the study of the ECS we realize that many hormones act on diverse physiological processes in the body. [15] 

Pancreatic cancer is the toughest to treat

Cancer of the pancreas is known to be one of the hardest to cure because early detection is almost impossible. This cancer is vicious and kills over 90% of its victims within five years. Researchers at Harvard University state that Cannabis killed all the tumor cells in 70% of mice with pancreatic cancer. These scientists were so surprised at the results that they had to run additional tests for confirmation. They published their research in the Journal Frontiers on Oncology in 2019.


Their findings are attributed to particular chemicals within Cannabis known as flavonoids and in particular Caflanone (FBL-03G). The American FDA has approved Caflanone ‘orphan drug’ status meaning that it can cure previously incurable diseases. This flavonoid successfully destroyed tumor progression in animals with pancreatic cancer and research is ongoing at Harvard Medical School. This proves that flavonoids are also involved in the apoptotic functions of the anticancer properties of Cannabis.

Jamaican ‘Black Swan’ is an ideal dagga strain to treat pancreatic cancer 

Doctors and scientists are starting to realize that Cannabis medicine is so much more than just THC and CBD. Terpenes and flavonoids within Cannabis all have their own special healing properties over and above the cannabinoids.


Dr. Henry Lowe is chairman of the pharmaceutical drug company known as Flavocure and he has studied Cannabis since 1974. He discovered a unique strain in Jamaica named ‘Black Swan’ because of its rich flavonoid content, particularly Caflanone. The company has isolated this strain specifically for their research in the treatment of pancreatic cancer. The most amazing fact about this treatment is that there are no side-effects, which is unheard of in pharmaceutical human trials. [16]

What do these three plants have in common to heal diabetes?

At the time of writing this paper (2021) there was not one single scientific paper referencing Sugarbush having anti-diabetic properties, not one! The search was relentless and eventually ii found a scientific link revealing the chemical responsible for anti-diabetic properties in many medicinal plants. 

This chemical is the terpene scientifically known as Linalool. As mentioned before terpenes are the chemicals within plants that are responsible for the aroma, fragrance and taste of plants and their fruits. Terpenes also have healing properties that contribute to the medicinal value of many herbs including Cannabis. Linalool is found in many plants like lavender, and is also the terpene responsible for sweet-tasting strawberries!

“Linalool can comprise up to 66% of the Proteas fruity scents.” [17]


No other plant on Earth contains this much Linalool and even ganja rarely presents more than 1.5%. It is exciting to discover that all three plants contain the chemical known as Linalool also found in hundreds of plants. This spicy lavender-resembling terpene is the secret molecular plant-link to regulating blood sugar in human beings. Sutherlandia also contains Linalool and this is what produces the much needed anti-diabetic properties of this plant. [18]

Equally exciting is that modern scientists are finally acknowledging the anti-diabetic properties of plants and their chemical components. Linalool is now scientifically proven as an effective plant derived anti-diabetic treatment. [19] These revelations bring joy to traditional healers who lack the resources to scientifically publish their own valuable disciplines of medicinal knowledge. Molecules like Linalool will surely lead to a terpene boom in the future because of their ancient healing properties.

Can we afford to not heal diabetes with herbs?

Healing diabetes by using plants has been part of folk medicine and traditional healing systems forever. If no proof prevailed to the healing abilities of herbs then they would not be studied for their potent hypoglycaemic effects. Herbal intervention is completely natural and is woven into the cultural fabric of indigenous peoples. Modern medicine is losing its worth in terms of being effective and people are becoming more interested in herbs and self-medicating.


Natural medicine is needed because it provides health maintenance and is nurturing as plants are...

Healing diabetes by serving herbal teas is the best preventative primary care that we can offer to our communities. In SA herbs are used by different healers, such as herbalists, diviners, Inyanga;s Rastafarians, alternative and allopathic healers, and even ordinary people. This creates unique situations where traditional knowledge and science meet in the mountains to provide insight into healing herbs. [20]

The good news is that by healing diabetes with herbs we stand an excellent chance of reducing numbers with the least cost to physical and mental side-effects. We must become conscious that we can heal ourselves from almost any known disease by taking responsibility for what we consume. Diabetes is a worldwide health crisis because of poor nutrition and it should be on the forefront of every country’s agenda.
