Aster yomena, an edible vegetable, is a perennial herb which grows throughout northeast Asia and Siberia.
It looks like young tea leaves and has a bitter taste.
The herb was found to be effective in relieving the symptoms of allergies.
When Korea's Rural Development Administration research team fed Aster yomena extracts to mice injected with allergens for four weeks, …the concentration of allergens was reduced by 70 percent.
Symptoms of atopic dermatitis, like red rashes and dry skin, were reduced by about 40 percent.
Clinical trials demonstrated the effectiveness of the extract in alleviating allergic conjunctivitis symptoms including sneezing and a runny nose …after six weeks.
"We saw a remarkable reduction in the thinning and festering of the skin, red spots and inflammation after the intake of Aster yomena."
Aster yomena has been used in traditional remedies to treat coughs and asthma, …but this is the first time that the effects have been scientifically proven.
The herb takes just about a month to harvest and can be grown up to seven times a year.
It's usually consumed by parboiling and lightly seasoning the shoots, …but it can also be made into tea or cookies.
The study was published in the Journal of Functional Foods and the Journal of the Chinese Medical Association.
