Though studies in the general population have not conclusively shown that vitamin C decreases your risk of the common cold, it does reduce the duration of symptoms by 8%.

Watercress
is a good source of vitamin C, which promotes a healthy immune system and
reduces your risk of infection.

Al-Imam Al-Hussein (peace be upon him) said: Do not say about your faithful brother when he is absent from you except what you would like him to say about you if you were absent from him.

Boosts Immune Function Thanks to High Vitamin C Levels.
Watercress contains 15 mg of vitamin C per cup (34 grams), which is 20% of the RDI for women and 17% for men.
Vitamin C is renowned for its beneficial effects on immune health. Deficiency in vitamin C has been linked to decreased immune function and increased inflammation.
Vitamin C boosts your immune system by increasing the production of white blood cells that fight infections.

Imam Ali (peace be upon him) said: Live amongst people in such a manner that if you die they weep over you and if you are alive they crave for your company.

Additionally, one cup (34 grams) of watercress provides more than 100% of the RDI for vitamin K.
Vitamin K is a component of osteocalcin, a protein that makes up healthy bone tissue and helps regulate bone turnover.
