A Traditional Remedy for Modern Diabetes Challenges
A simple berry, long cherished in folk medicine, is capturing scientific attention for its potential in managing one of today's most prevalent health conditions.
For centuries, hawthorn has been revered in traditional medicine systems worldwide—from ancient European herbalism to Traditional Chinese Medicine—primarily for its cardiovascular benefits. Today, this humble shrub is gaining recognition for a different therapeutic potential: managing type 2 diabetes and its associated metabolic complications.
In Jordan, where diabetes affects nearly 20% of the adult population, researchers are investigating hawthorn as a potential complementary approach to metabolic health. The bright red berries, known as "shanzha" in Chinese medicine, are now the subject of rigorous scientific inquiry, particularly for their effects on blood sugar control and cholesterol levels.
Type 2 diabetes has reached pandemic proportions globally, characterized by the body's inability to properly manage insulin secretion or function. The condition manifests as chronic hyperglycemia (elevated blood sugar) which, if left unmanaged, can lead to severe complications including cardiovascular disease, nerve damage, kidney failure, and vision problems.

Key bioactive compound classes in hawthorn
These compounds work synergistically to provide antioxidant, anti-inflammatory, and potentially glucose-regulating effects, making hawthorn a compelling subject for diabetes research.
A significant clinical investigation conducted in Jordan set out to scientifically validate hawthorn's traditional use in metabolic disorders. The study aimed to measure the effects of hawthorn supplementation on key diabetes markers: hemoglobin A1c (HbA1c, a measure of long-term blood sugar control) and blood lipid levels.
The research team employed a structured clinical approach with participants receiving 500mg capsules three times daily with meals (breakfast, lunch, and dinner).
The findings from the Jordanian study demonstrated substantial improvements across multiple metabolic parameters after 12 weeks of hawthorn supplementation.
| Parameter | Before Treatment | After 12 Weeks | Change |
|---|---|---|---|
| Fasting Blood Glucose (mg/dL) | 223.6 | 186.34 | -16.7% |
| HbA1c (%) | 8.5% | 7.2% | -15.3% |
The significant reduction in HbA1c is particularly noteworthy, as this marker reflects average blood sugar levels over the preceding 2-3 months. The decrease from 8.5% to 7.2% represents a meaningful clinical improvement that could potentially reduce diabetes complication risks.
| Lipid Parameter | Before Treatment (mg/dL) | After 12 Weeks (mg/dL) | Change |
|---|---|---|---|
| Triglycerides (TG) | 235.5 | 160.0 | -32.1% |
| Total Cholesterol (TC) | 310.0 | 187.6 | -39.5% |
| LDL Cholesterol | 155.2 | 115.5 | -25.6% |
| HDL Cholesterol | 52.4 | 69.2 | +32.1% |
Reduction in Total Cholesterol
Increase in HDL Cholesterol
The lipid profile improvements are striking, with hawthorn supplementation leading to substantial reductions in atherogenic lipids (LDL and triglycerides) while simultaneously boosting protective HDL cholesterol. This dual benefit addresses two major cardiovascular risk factors commonly associated with diabetes.
Modern pharmacological studies have begun to unravel the mechanisms behind hawthorn's potential antidiabetic effects. The plant's rich cocktail of bioactive compounds appears to influence multiple physiological pathways relevant to metabolic health.
Hawthorn extracts may enhance insulin sensitivity by increasing the phosphorylation of glucose transporter 4 (GLUT4) and insulin receptor substrate 1, key components in cellular glucose uptake 1 .
Studies suggest that hawthorn components activate AMP-activated protein kinase (AMPK), often described as a "metabolic master switch" 2 .
The flavonoids and proanthocyanidins in hawthorn demonstrate potent antioxidant activity, scavenging free radicals and reducing oxidative stress 3 .
Chronic inflammation plays a crucial role in insulin resistance. Hawthorn compounds have been shown to attenuate pro-inflammatory cytokines 4 .
| Compound Class | Specific Examples | Potential Metabolic Effects |
|---|---|---|
| Flavonoids | Vitexin, Quercetin, Hyperoside | Antioxidant, anti-inflammatory, insulin sensitizing |
| Proanthocyanidins | Procyanidin B2, Epicatechin | Antioxidant, cholesterol regulation |
| Triterpenoids | Ursolic acid, Oleanolic acid | Anti-inflammatory, glucose regulation |
| Phenolic Acids | Chlorogenic acid, Caffeic acid | Antioxidant, glucose modulation |
An important advantage of hawthorn is its favorable safety profile. Traditional use and modern toxicological studies indicate low toxicity, with one study noting an acute oral toxicity of 6g/kg in humans—far exceeding typical supplemental doses 5 .
Well-tolerated in traditional and modern use
Potential interactions with cardiovascular medications
Composition varies based on plant part and preparation
The investigation into hawthorn's effects on HbA1c and lipid levels in Jordanian diabetic patients represents an important intersection of traditional medicine and modern scientific validation. With its dual action against both hyperglycemia and hyperlipidemia, hawthorn offers a promising complementary approach to diabetes management—addressing not only blood sugar control but also the associated cardiovascular risk factors that make diabetes particularly dangerous 6 .
Future research needs to address several important questions:
As research continues to evolve, this ancient remedy may find new relevance in addressing one of our most pressing modern health challenges. For the millions living with type 2 diabetes worldwide, hawthorn represents yet another example of how nature's pharmacy might contribute to human health when subjected to rigorous scientific investigation.
