What is Astragalus? 

Astragalus comes from the roots of its parent plant. It belongs to the pea family, with over 2,000 species all over the world. The two main types used for medicinal benefits are Astragalus membranaceus and Astragalus mongholicus. Found in China, Mongolia, and Korea, this perennial herb can grow up to 16 to 36 inches high. It has hairy stems and leaves with 12 to 18 pairs of leaflets. 

Dating back over 2,000 years, Astragalus has deep roots in Chinese medicine. Its Chinese name, huáng qí means “yellow life energy”. It shows its standing as a potent herb. People use it traditionally to make their bodies stronger against diseases. Often, they mix it with other herbs to enhance the effect. 

While there are over 2,000 species of Astragalus, only two are used for their medicinal value. These are Astragalus membranaceus and Astragalus mongholicus. They grow in China, Korea, and Japan. The dried root is reaped from the mature plants (aged four to seven years). It is then used in dietary supplements, extracts, and remedies. 

Nutritional Profile of Astragalus 

Astragalus carries many active plant compounds that are suggested to give it its health perks. The three key active compounds in the Astragalus species are: 

1. Polysaccharides: Complex carbs linked to boosting the immune system and antioxidant effects. 

2. Flavonoids: Plant chemicals known for health perks seen in fruits and veggies. They may have anti-inflammatory, antidiabetic, and antioxidant traits. 

3. Saponins: Compounds that could lower cholesterol and fight cancer. 

Researchers have also found other compounds in the Astragalus plant. These include sterols, amino acids, volatile oils, and trace minerals like zinc, iron, copper, manganese, vanadium, and tin.

• Dosage for heart health benefits 

As with immune support, the best dosage for heart health is still unclear. Always talk to a health expert before starting to take any supplement. 

3. Alleviating Chemotherapy Side Effects 

Chemotherapy is a key treatment for many cancer patients. But it can lead to severe side effects. Astragalus may help reduce effects like nausea, vomiting, diarrhea, and fatigue. 

• Potential benefits for cancer patients 

Astragalus is found to reduce nausea, vomiting, and diarrhea in a study. Also, in another study, it was found to help lessen extreme tiredness during the first week of chemotherapy. 

It’s not clear how Astragalus may help lower chemotherapy side effects. However the plant’s active compounds like polysaccharides and saponins might be beneficial. 

• Research-based evidence for reducing chemotherapy side effects 

Even though these studies show promise, we need more research. We need to confirm these findings and to know the right dosage. 

4. Controlling Blood Sugar Levels 

Scientists are looking at whether Astragalus affects blood sugar levels, especially in managing type 2 diabetes. The plant’s active compounds like polysaccharides and flavonoids might aid insulin sensitivity and glucose metabolism. 

• Anti-diabetic properties 

Research says that astragalus supplements might help manage blood sugar levels in type 2 diabetics. In animal and lab studies, Astragalus improved sugar metabolism and lowered blood sugar levels. 

• Insulin sensitivity and resistance 

Astragalus might improve insulin sensitivity and lower insulin resistance, which are key to managing type 2 diabetes. By improving these factors, Astragalus might offer another option for diabetics. 

• Research-based Evidence in Diabetes Management  

Some studies hint Astragalus might help in managing diabetes. It could improve the effects of usual treatments. However we need more research to confirm these early findings and find out the best dosage.
