Tonguibogam, an encyclopedia of traditional medicine of Korea, says corbicula is efficacious for weakness, enervation and indigestion.

In particular, it is good in dissolving poisonous substances in liver.

Corbicula spawns in summer.

Koreans gather Corbicula for food or medicinal material after its spawning days.

A health drink was developed with its medicinal ingredients as main substances.

Thak Un Ju, a researcher at Pyongyang Medical College of Kim Il Sung University, told KCNA that corbicula includes taurine, glycogen, anticancer materials and essential amino acid.

She made liver-protection liquid with corbicular, which helps enhance immunity and improve health conditions.

Corbicular gives a good effect on bladder, stomach and eyesight.
