The human body stores only a small amount of vitamin C, and when deficiencies occur, it can lead to certain health conditions. The symptoms of vitamin C deficiency include bleeding gums, mood swings, painful joints, fatigue, oxidative stress, and weight gain.

Luckily, nasturtium contains vitamin C which reduces a person’s risk of contracting infections, boosts immunity, lower chronic inflammation, detoxifies the body, and decreases oxidative damage.  Due to its rich vitamin C content, nasturtium is able to combat coughs, flu, and cold.
