Chicken is the most common type of poultry in the world. Owing to the relative ease and low cost of raising chickens—compared to mammals such as cattle or hogs—chicken meat (commonly called just "chicken") and chicken eggs have become prevalent in numerous cuisines.

Some indications that can be reduced by chicken based on TCM are:

   * Qi vacuity: pale face, fatigue, quiet voice, sweating during the day, lack of strength, easily exhausted.

   * Blood vacuity (generally associated with qi vacuity): dull, pale complexion; difficulty concentrating, numbness, muscle weakness, heart palpitations, amenorrhea (lack of menstruation) or hypomenorrhea (scant menstruation), general weakness, emotional instability, and depression.

   * Qi and blood vacuity following childbirth: lack of strength, postnatal depression, heart palpitations, dizziness, and lack of milk flow after giving birth.

   * Stomach qi and spleen qi vacuity: general lack of strength; loss of strength following long, draining illness; infirmity in old age, decreased appetite, indigestion, diarrhea, and edema.

   * Stomach cold or spleen yang vacuity: the cold sensation in the body, especially in the stomach region, cold extremities, and lack of appetite.

   * General vacuity of kidney network: weakness and pain in knees and hip, premature ejaculation, tinnitus, and frequent urination.
