Why Japanese Knotweed is a Springtime Favorite
The young shoots of Japanese Knotweed are packed with health benefits. Rich in antioxidants, they help reduce inflammation and support your immune system.

Preparation Steps:
Peel off the tough outer skin of the shoots.
Rinse thoroughly to remove any dirt.
Parboil the shoots to mellow out their tartness and prepare them for cooking.
