Herbs for a Strong Immune Defense: Preparing for Flu Season

As flu season approaches, strengthening your immune system becomes a priority to defend against seasonal illnesses. Alongside vaccination, proper hygiene, and a healthy lifestyle, certain herbs have been recognized for their ability to enhance immune function and provide a natural defense against viruses and bacteria.

Understanding the Immune System

The immune system is a complex network of cells, tissues, and organs that work together to defend the body against harmful pathogens.

Factors such as nutrition, sleep, stress, and exercise all play a role in immune health.
