Yin Chen Overview
Yin chen (Artemisia capillaris) is an herb that is native to East Asia and is commonly used in traditional Chinese medicine (TCM). It is also known as "hairy wormwood" or "capillary wormwood," due to the fine, hair-like leaves of the plant.
Yin Chen is purported to have a number of medicinal properties and is used to treat a variety of ailments, including digestive disorders, respiratory infections, and skin conditions. It is also believed to have antibacterial, antiviral, and anti-inflammatory effects, and is often used to boost the immune system and promote healing. Yin chen is typically consumed as a tea or in a powdered supplement form. Yin Chen is a component of the popular 'Yin-care Herbal Wash' product.
Chlorpromazine Overview
-
Chlorpromazine is used to treat the symptoms of schizophrenia (a mental illness that causes disturbed or unusual thinking, loss of interest in life, and strong or inappropriate emotions) and other psychotic disorders (conditions that cause difficulty telling the difference between things or ideas that are real and things or ideas that are not real) and to treat the symptoms of mania (frenzied, abnormally excited mood) in people who have bipolar disorder (manic depressive disorder; a condition that causes episodes of mania, episodes of depression, and other abnormal moods). Chlorpromazine is also used to treat severe behavior problems such as explosive, aggressive behavior and hyperactivity in children 1 to 12 years of age. Chlorpromazine is also used to control nausea and vomiting, to relieve hiccups that have lasted one month or longer, and to relieve restlessness and nervousness that may occur just before surgery. Chlorpromazine is also used to treat acute intermittent porphyria (condition in which certain natural substances build up in the body and cause stomach pain, changes in thinking and behavior, and other symptoms). Chlorpromazine is also used along with other medications to treat tetanus (a serious infection that may cause tightening of the muscles, especially the jaw muscle). Chlorpromazine is in a class of medications called conventional antipsychotics. It works by changing the activity of certain natural substances in the brain and other parts of the body.
