Realgar-Indigo Naturalis
Realgar/Indigo naturalis (RIF), also known as Compound Huangdai (), is a medication used to treat acute promyelocytic leukemia. Effectiveness appears similar to arsenic trioxide. It is generally used together with all-trans-retinoic acid (ATRA). It is taken Oral administration, by mouth. Side effects may include abdominal pain and rash. It is made up of a combination of realgar (tetra-arsenic tetra-sulfide), ''Indigo naturalis'', radix salviae miltiorrhizae, root of ''Salvia miltiorrhiza'', and radix pseudostellariae, root of ''Pseudostellaria heterophylla''. It works by breaking down the cancer protein retinoic acid receptor alpha. The main active ingredients according to NCI are tetraarsenic tetrasulfide (realgar), indirubin (from the indigo) and tanshinone IIA (from the ''Salvia''). Realgar-Indigo naturalis was developed in the 1980s and approved for medical use in China in 2009. It is on the WHO Model List of Essential Medicines, World Health Organization's List of Essentia ...

Arsenic
Arsenic is a chemical element with the symbol As and atomic number 33. Arsenic occurs in many minerals, usually in combination with sulfur and metals, but also as a pure elemental crystal. Arsenic is a metalloid. It has various allotropes, but only the gray form, which has a metallic appearance, is important to industry. The primary use of arsenic is in alloys of lead (for example, in car batteries and ammunition). Arsenic is a common n-type dopant in semiconductor electronic devices. It is also a component of the III-V compound semiconductor gallium arsenide. Arsenic and its compounds, especially the trioxide, are used in the production of pesticides, treated wood products, herbicides, and insecticides. These applications are declining with the increasing recognition of the toxicity of arsenic and its compounds. A few species of bacteria are able to use arsenic compounds as respiratory metabolites. Trace quantities of arsenic are an essential dietary element in rats, ham ...

Radix Pseudostellariae
''Pseudostellaria heterophylla'', known commonly as ''hai er shen'' (, kid ginseng, child ginseng), ''tai zi shen'' (, crown prince ginseng), and false starwort, is an adaptogen in the family Caryophyllaceae that is used in Chinese medicine and herbalism to tonify the qi and generate yin fluids. It is known as the "ginseng of the lungs". The plant is a low growing plant of the pink family that is grown in Southern China in the provinces of Jiangsu, Anhui, Shandong, Heilongjiang, Jilin, Liaoning, Hebei, Henan, Shaanxi, Zhejiang, Jiangxi, Hubei, and Shanxi. Ethnobotany ''Haiershen'' is a relatively recent addition to the ''Chung Yao Chi New Chinese Materia Medica'' (), having been officially added in 1959, based upon local and ethnic use. It is weaker than ''Panax ginseng''. The herb is a mild adaptogen, demulcent, an immune tonic, nutritive, and a pectoral herb. In Chinese terms it tonifies the yin. Accordingly, the herb is restorative for lung damage due to excess heat or dr ...

Cancer Treatments
Cancer can be treated by surgery, chemotherapy, radiation therapy, hormonal therapy, targeted therapy (including immunotherapy such as monoclonal antibody therapy) and synthetic lethality, most commonly as a series of separate treatments (e.g. chemotherapy before surgery). The choice of therapy depends upon the location and grade of the tumor and the stage of the disease, as well as the general state of the patient (performance status). Cancer genome sequencing helps in determining which cancer the patient exactly has for determining the best therapy for the cancer. A number of experimental cancer treatments are also under development. Under current estimates, two in five people will have cancer at some point in their lifetime. Complete removal of the cancer without damage to the rest of the body (that is, achieving cure with near-zero adverse effects) is the ideal, if rarely achieved, goal of treatment and is often the goal in practice. Sometimes this can be accomplished by sur ...

Arsenic Compounds
Compounds of arsenic resemble in some respects those of phosphorus which occupies the same group (column) of the periodic table. The most common oxidation states for arsenic are: −3 in the arsenides, which are alloy-like intermetallic compounds, +3 in the arsenites, and +5 in the arsenates and most organoarsenic compounds. Arsenic also bonds readily to itself as seen in the square As ions in the mineral skutterudite. In the +3 oxidation state, arsenic is typically pyramidal owing to the influence of the lone pair of electrons. Inorganic compounds One of the simplest arsenic compound is the trihydride, the highly toxic, flammable, pyrophoric arsine (AsH3). This compound is generally regarded as stable, since at room temperature it decomposes only slowly. At temperatures of 250–300 °C decomposition to arsenic and hydrogen is rapid.Greenwood and Earnshaw, pp. 557–558 Several factors, such as humidity, presence of light and certain catalysts (namely aluminium) faci ...

Herbal Remedy
Herbal medicine (also herbalism) is the study of pharmacognosy and the use of medicinal plants, which are a basis of traditional medicine. With worldwide research into pharmacology, some herbal medicines have been translated into modern remedies, such as the anti-malarial group of drugs called artemisinin isolated from ''Artemisia annua'', a herb that was known in Chinese medicine to treat fever. There is limited scientific evidence for the safety and efficacy of plants used in 21st century herbalism, which generally does not provide standards for purity or dosage. The scope of herbal medicine commonly includes fungal and bee products, as well as minerals, shells and certain animal parts. Herbal medicine is also called phytomedicine or phytotherapy. Paraherbalism describes alternative and pseudoscientific practices of using unrefined plant or animal extracts as unproven medicines or health-promoting agents. Paraherbalism relies on the belief that preserving various substances f ...

WHO Model List Of Essential Medicines
The WHO Model List of Essential Medicines (aka Essential Medicines List or EML), published by the World Health Organization (WHO), contains the medications considered to be most effective and safe to meet the most important needs in a health system. The list is frequently used by countries to help develop their own local lists of essential medicines. , more than 155 countries have created national lists of essential medicines based on the World Health Organization's model list. This includes both developed and developing countries. The list is divided into core items and complementary items. The core items are deemed to be the most cost-effective options for key health problems and are usable with little additional health care resources. The complementary items either require additional infrastructure such as specially trained health care providers or diagnostic equipment or have a lower cost–benefit ratio. About 25% of items are in the complementary list. Some medicatio ...

Retinoic Acid Receptor Alpha
Retinoic acid receptor alpha (RAR-α), also known as NR1B1 (nuclear receptor subfamily 1, group B, member 1) is a nuclear receptor that in humans is encoded by the ''RARA'' gene. NR1B1 is a gene with a protein product and has a chromosomal location of 17q21.2. RARA codes for the nuclear hormone receptor Retinoic Acid Receptor, Alpha subtype, and are themselves transcription factors. There are another 2 subtypes of RARs, Beta subtype, and Gamma subtype. Function Retinoid signaling is transduced by 2 families of nuclear receptors, retinoic acid receptor ( RAR) and retinoid X receptor ( RXR), which form RXR/RAR heterodimers. In the absence of ligand, DNA-bound RXR/RARA represses transcription by recruiting the corepressors NCOR1, SMRT ( NCOR2), and histone deacetylase. When ligand binds to the complex, it induces a conformational change allowing the recruitment of coactivators, histone acetyltransferases, and the basic transcription machinery. Retinoic Acid Receptor Alpha, th ...

Traditional Chinese Medicine
Traditional Chinese medicine (TCM) is an alternative medical practice drawn from traditional medicine in China. It has been described as "fraught with pseudoscience", with the majority of its treatments having no logical mechanism of action. Medicine in traditional China encompassed a range of sometimes competing health and healing practices, folk beliefs, literati theory and Confucian philosophy, herbal remedies, food, diet, exercise, medical specializations, and schools of thought. In the early twentieth century, Chinese cultural and political modernizers worked to eliminate traditional practices as backward and unscientific. Traditional practitioners then selected elements of philosophy and practice and organized them into what they called "Chinese medicine" (''Zhongyi''). In the 1950s, the Chinese government sponsored the integration of Chinese and Western medicine, and in the Great Proletarian Cultural Revolution of the 1960s, promoted Chinese medicine as inexpensive a ...

Indigo Naturalis
Indirubin is a chemical compound most often produced as a byproduct of bacterial metabolism. For instance, it is one of the compounds responsible for the generally benign condition purple urine bag syndrome, resulting from bacteria metabolizing indoxyl sulfate found naturally in urine. Indirubin is a structural isomer (more precisely is position isomer) of indigo dye. Indigo naturalis Indirubin is a chemical constituent of indigo naturalis (also known as qing dai ), which has been used since 627 AD in traditional Chinese medicine. It is essentially the indigo dye as traditionally extracted from plants by fermentation and lime treatment. The dye mixture contains a variety of organic compounds, indirubin and tryptanthrin being possible sources of some pharmacological actions. It is used in realgar/Indigo naturalis, a medication for acute promyelocytic leukemia. Research Indirubin exerts its effects on the human body by downregulating expression of genes.
