Yin Chen is contraindicated for those who have blood stasis and yellowing and those with blood deficiency and yellowing, and should not be consumed in large quantities by those with weak spleen and stomach.
It is bitter, pungent and slightly cold in nature, and is mainly effective in clearing dampness and heat and reducing jaundice, but it should be used with caution by people with yellowing of the blood and those with blood deficiency and atrophy.
Yellowish blood refers to people with yellowish skin color, sunken pulse and dark stools, which are commonly found in patients with typhoid fever (diseases caused by fever due to feeling of cold); yellowish blood refers to people with excessive blood loss and pale, waxy face, such as women with excessive menstrual bleeding.
In addition, it should be noted that Yin Chen is slightly cold in nature, and its consumption in large quantities by people with weak spleen and stomach may cause gastrointestinal discomforts, so it should be consumed in a reasonable manner so as not to cause discomforts. It is recommended to seek medical advice from a Chinese medicine practitioner to avoid self-medication.
