Plant-Based Foods That Boost Your Immunity

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.
