A strong immune is all we need during autumn and winter. Astragalus is a plant of Chinese medicine that is used both to strengthen body as as also to treat viral infections.
What is astragalus
For many centuries, astragalus has been used for its adjuvant properties. It can be used either alone or in combination with other immune-stimulating herbs such as echinacea and pau d'arco. The active part of the plant is the root. Astragalus is rich in saponins or otherwise known as astragalosides, polysaccharides and flavonoids, such as quersentin and phytosterols, which give it many properties.
Like most of the herbs, astragalus has many properties:
Thanks to its composition in flavonoids, astragalus has strong antioxidant properties. It neutralizes the action of free radicals by protecting cells from oxidative damage.

Polysaccharides and saponins have powerful anti-inflammatory effects. Chronic inflammation is the main causative factor of many chronic diseases. Due to its anti-inflammatory action, astragalus is considered as a very potent supplement for treating and preventing the onset of cardiovascular disease, diabetes and even cancer.

Some studies have shown that astragalus helps reduce serum triglycerides as well as blood pressure. Regarding cancer, astragalus exhibit anti-tumor properties, help to improve the action of anticancer drugs, and it also appears to reduce fatigue caused by chemotherapy.

It also appears to reduce apoptosis of β-cells οf pancreas, raising questions about the role it can play in diabetes type 1. However, more studies are needed to confirm the above actions.
