Plant-Based Foods That Boost Your Immunity
Ginger

Ginger produces an internal warming effect for the body and fights the buildup of toxins in the organs, particularly in the respiratory system, lymphatic system and sinuses. Ginger also possesses potent antioxidant, anti-inflammatory and antimicrobial properties that make it suitable for boosting the immune system and for the repair of damaged cells.
Cayenne

Cayenne contains various valuable compounds, including capsicum, beta carotene and antioxidants. Capsicum provides vitamin C and flavonoids that fight flu and cold viruses, while beta carotene and antioxidants fight bacteria in the mucus membrane tissue. Cayenne also increases the body temperature and causes you to sweat to release toxins, hence boosting the immune system.
