Overweight and obesity have become structural health problems worldwide that are linked to numerous chronic diseases. The pressure to lose weight effectively is growing, especially as more people actively choose a healthier lifestyle. In this search, surprising substances sometimes emerge. Halofuginon (HF), a natural compound from the Changshan plant, is being studied increasingly seriously in this context.
The Changshan root, derived from Dichroa febrifuga Lour, has been used for over 2,000 years in traditional Chinese medicine — originally against fever and malaria. Only in recent years have researchers focused their attention on a completely different area: the potential of this plant in the context of obesity and metabolic problems.

A research team led by Professor Jianping Weng (University of Science and Technology of China) recently achieved a remarkable breakthrough. Together with John R. Speakman from the Shenzhen Institutes of Advanced Technology, they analyzed the effects of HF in relation to obesity. Their findings, published in *Science Advances*, show that HF influences two key factors within energy metabolism.
These are GDF15 (growth factor 15) and FGF21 (fibroblast growth factor 21) — proteins involved in appetite regulation and fat burning. By stimulating these substances, the researchers observed clear improvements in metabolism and a reduction in body weight. The combination of reduced appetite and increased energy expenditure makes HF particularly interesting for further research.
Research in Mice
Researchers accidentally discovered during a preclinical experiment that HF had a safe effect on weight loss in mice. This finding led to more extensive research within a diet-induced obesity (DIO) model. The results were convincing enough to look further into the underlying mechanisms.
The analysis revealed that GDF15 reduces food intake. This substance is known as an ‘anorexigenic factor’ because of its influence on appetite. The mechanism of action focuses on the GFRAL receptor in the brain, a specific target for regulating hunger.
Glossary
- Halofuginon: A substance from the Changshan plant, potentially useful against obesity.
- Metabolism: All processes in the body that convert and use energy.
- Obesity: Severe overweight with a BMI above 30.
- Preclinical: Research conducted before testing on humans, often on animals.
- Endogenous: Originating from within the body.
The Mechanism Behind Weight Loss
Another involved substance, FGF21, proved to have effects on multiple fronts: it increases energy expenditure, improves insulin sensitivity, and influences metabolism in both liver and fat tissue. This protein is produced in the liver and functions as a regulatory hormone within energy metabolism.
The combined effect of HF stems from increasing the body’s own (endogenous) production of both GDF15 and FGF21. That dual action — less appetite and more energy expenditure — proves essential. Notably, stimulating these substances through molecular means is cheaper and more practical than administering expensive protein medications, such as recombinant GDF15 or FGF21. This can also improve treatment adherence in the long term.
Sustained Metabolic Benefits
In the DIO mouse model, researchers observed consistent body weight reduction and notable improvement in energy metabolism. FGF21 played a key role by stimulating fat burning and enhancing insulin sensitivity.
What stood out was the robustness of the effect. The results held up regardless of the mouse’s sex, method of administration, or model type — whether DIO mice, ob/ob mice, or DIO minipigs. Even differences in ambient temperature during feeding proved to have no effect.
The team also found that HF enhanced the expression and release of GDF15 and FGF21 by acting on stress pathways within the body. When these substances were experimentally disabled, the weight loss effect of HF noticeably decreased. HF likely works as an inhibitor of the enzyme EPRS1, a potential direct target for stimulating these processes.
Interestingly, MAZ-negative compounds had no effect on weight or on the elevation of GDF15 and FGF21. They could not inhibit EPRS1, making this pathway an important molecular target within obesity research.
The results support the idea that HF — and chemically derived variants — have potential as future obesity medications. The shift from antimalarial drug to metabolic process regulator underscores how insights from traditional Chinese medicine increasingly play a role in modern pharmacology.
