Table 2.

The table below highlights the various properties and the mechanism of action of quercetin.

S.No.	Properties	Mechanism of Action	References
1	Anti-inflammatory	Increase the IFN-γ cells expression and decreases IL-4 positive cell expression.	[59]
2	Anti-cancer	Induces extrinsic and intrinsic pathways of apoptosis, autophagy, and arrests cell cycle.	[60]
3	Anti-oxidant	Regulates the level of GSH. Downregulates MDA level and upregulates the activity of SOD. Quercetin is the scavenger of free radicals.	[54,55]
4	Anti-hypertensive	Lowers hypertensive severity by reducing nitric oxide, TNF-α, and IL-6 concentrations.	[61]
5	Anti-diabetic	Quercetin reduces the concentration of blood glucose levels, preserves the function of islets cells, number of β cell numbers in diabetic mice.	[62]
6	Neurodegenerative	alleviates neuronal oxidative damage and neuroinflammation and shows anti-dementia and neuroprotective effects.	[62]
