Emodin
Emodin (6-methyl-1,3,8-trihydroxyanthraquinone) is a chemical compound, of the anthraquinone family, that can be isolated from rhubarb, buckthorn, and Japanese knotweed ('' Reynoutria japonica'' syn. ''Polygonum cuspidatum''). Emodin is particularly abundant in the roots of the Chinese rhubarb (Rheum palmatum), knotweed and knotgrass (Polygonum cuspidatum and multiflorum) as well as Hawaii ‘au‘auko‘i cassia seeds or coffee weed (Semen cassia). It is specifically isolated from Rheum palmatum L. It is also produced by many species of fungi, including members of the genera ''Aspergillus'', ''Pyrenochaeta'', and '' Pestalotiopsis'', inter alia. The common name is derived from ''Rheum emodi'', a taxonomic synonym of '' Rheum australe'', (Himalayan rhubarb) and synonyms include emodol, frangula emodin, rheum emodin, 3-methyl-1,6,8-trihydroxyanthraquinone, Schüttgelb (Schuttgelb), and Persian Berry Lake. Pharmacology Emodin is an active component of several plants used in Tradit ...

Rhubarb
Rhubarb is the fleshy, edible stalks ( petioles) of species and hybrids (culinary rhubarb) of '' Rheum'' in the family Polygonaceae, which are cooked and used for food. The whole plant – a herbaceous perennial growing from short, thick rhizomes – is also called rhubarb. Historically, different plants have been called "rhubarb" in English. The large, triangular leaves contain high levels of oxalic acid and anthrone glycosides, making them inedible. The small flowers are grouped in large compound leafy greenish-white to rose-red inflorescences. The precise origin of culinary rhubarb is unknown. The species '' Rheum rhabarbarum'' (syn. ''R. undulatum'') and '' R. rhaponticum'' were grown in Europe before the 18th century and used for medicinal purposes. By the early 18th century, these two species and a possible hybrid of unknown origin, ''R.'' × ''hybridum'', were grown as vegetable crops in England and Scandinavia. They readily hybridize, and culina ...

Glossostemon Bruguieri
''Glossostemon bruguieri'' or ''Dombeya arabica'' is a species of flowering plant in the family Malvaceae. It is a shrub with thick long tapering dark colored roots with 70–100 cm in length and 5–8 cm in breadth, found in Yemen, Iran, Iraq, Egypt, Saudi Arabia, Turkey and Morocco. The dried peeled roots of ''G. bruguieri'' are called in Egypt and Arab countries ( ar, مُغات ). The roots are commonly used in traditional medicine for many nutritional and medicinal values. Chemical composition Starch is the main component of the dried peeled roots with 54.5–62.4% (differs according to the climatic region of cultivation) while protein represents 4.5–8.3%, half of which is aspartic acid. Roots contain high amounts of non-starch polysaccharides including dietary fibers, pectin and up to 27% of mucilage. Calcium, magnesium and iron are the main minerals of the roots. Minor amounts of zinc, manganese and copper have also been found. Tatakin (4-methoxyisoscutell ...

Antiviral
Antiviral drugs are a class of medication used for treating viral infections. Most antivirals target specific viruses, while a broad-spectrum antiviral is effective against a wide range of viruses. Unlike most antibiotics, antiviral drugs do not destroy their target pathogen; instead they inhibit its development. Antiviral drugs are one class of antimicrobials, a larger group which also includes antibiotic (also termed antibacterial), antifungal and antiparasitic drugs, or antiviral drugs based on monoclonal antibodies. Most antivirals are considered relatively harmless to the host, and therefore can be used to treat infections. They should be distinguished from viricides, which are not medication but deactivate or destroy virus particles, either inside or outside the body. Natural viricides are produced by some plants such as eucalyptus and Australian tea trees. Medical uses Most of the antiviral drugs now available are designed to help deal with HIV, herpes viruses, the h ...
