Benefits & evidence
2 claims · 0 sources- Swede is traditionally used to support immune function, likely due to its vitamin C and other antioxidant properties which help in the modulation of inflammatory responses.
Vitamin C acts as a potent antioxidant, scavenging free radicals and protecting cells from oxidative stress. It also plays a role in enhancing immune cell functions such as phagocytosis and cytokine production.
- Swede, a Brassica species traditionally used in European folk medicine, may help support digestion due to its glucosinolate content which can aid in the breakdown of food and stimulate digestive enzymes.
Glucosinolates are sulfur-containing compounds that break down into isothiocyanates upon enzymatic action. These compounds have been shown to activate the transcription factor Nrf2, promoting antioxidant responses and enhancing detoxification pathways in the gut.
