Yin Chen is used for clearing dampness-heat, relieving bile and relieving jaundice, and can be used for treating jaundice, dampness-warmth, summer-dampness and itching of wet sores; jujube is used for tonifying the middle Jiao, nourishing the blood, nourishing blood and tranquillizing the mind, and can be used for treating deficiency of the spleen with less food, and loose stools (thinning of feces and lack of shape). Yin Chen is the dried above-ground part of Artemisia binatae or Artemisia sinensis, family Asteraceae, which has the effect of clearing dampness and heat, inducing diuresis and relieving yellowness, and is beneficial to improving or treating jaundice with low urine output, dampness, warmth and summer dampness, and itchy wet sores. However, Yin Chen should be used with caution for those with blood deficiency and yellowing. Jujube is the dried mature fruit of Ziziphus jujuba, which has the effect of tonifying the middle Jiao, nourishing the blood and tranquilizing the mind, and can be used to treat or improve the symptoms of spleen deficiency with low food intake, weak and loose stools, and women with dirty and restlessness. However, jujube helps dampness and generates heat, which makes people full, so it is not suitable for people who are full of dampness (too much dampness causing fullness and discomfort in the spleen and stomach) or those who have stagnation and phlegm-heat. It is worth reminding that the choice of Chinese herbs should be under the guidance of a professional Chinese medicine practitioner in order to prevent the use of medication errors, which may bring adverse effects to the body.
