New bioactive peptides, demonstrating anti-viral activity for dengue, isolated from 33 Thai medicinal plants, were identified (Panya et al. 2019). Among the tested extracts, Acacia catechu L. peptides showed the most pronounced anti-DENV activity. A. catechu L. is a legume species of the genus Acacia, belonging to the Fabaceae family, an Asian medicinal plant, whose seeds are a good source of protein. Two bioactive peptides isolated from A. catechu L. inhibited the formation of DENV foci by more than 90%. The authors reported that the two peptides are recommended for further investigation as antivirals against DENV infection. The extract of the Asian medicinal plant Houttuynia cordata T., known as fish mint, prevented dengue virus infectivity (Xie et al. 2013; Chiow et al. 2016).

Kani tribes are situated in Kouthalai of Tirunelveli hills, Tamil Nadu, India. They have practical knowledge about their TM plants. The combination of A. conyzoides leaf juice and Cocculus hirsutus is used to treat diarrhea. A mixture of Borreria ocymoides leaf juice, Garcinia pictoria leaf juice, and Syzigium cumini stem bark, along with gingerly oil is prepared as a paste and applied to wounds. Carmona retusa leaf powder is primarily useful for cleaning teeth. The whole plant is mixed with Acacia nilotica leaves and the seeds of Areca catechu and then used to cure toothache and to fortify teeth. Skin diseases are easily cured by a formulation of Crotalaria pallida leaf powder and root bark along with Tragia involucrata and Wrightia tinctoria leaves. This paste can be used externally to cure skin diseases. Scleropyrum pentandrum stem bark and leaves are also used to treat skin diseases. Extracted oil from Pongamia pinnata and the leaf paste from Eupatorium odoratum are mixed thoroughly and applied to wounds.
Abies Spectabilis (D. Don) G. Don (Syn. A. Webbiana Lindl.) Family: Coniferae
Published in L.D. Kapoor, Handbook of Ayurvedic Medicinal Plants, 2017
Medicinal properties and uses — The wood extract, known as katha, is very useful in chronic diarrhea and dysentery, bleeding piles, uterine hemorrhage, leukorrhea, and gleet, in doses of 0.5 to 1.5 g. Catechu is very efficacious for mercurial salivation, bleeding or ulcerated or spongy gums, hypertrophy of the tonsils, and ulceration of the mouth. It may be used as a lozenge. An infusion of catechu is a very useful douche in uterine hemorrhage, leukorrhea, and gonorrhea. Tincture of catechu is particularly useful for bed sores and painful mammary glands. A mixture of catechu and myrh is used as a tonic and as a galactagogue for nursing mothers. This plant is also alleged to have antiseptic and antidysenteric properties.1

Catechin is a plant-derived phenolic secondary metabolite that has been derived from catechu (the tannic juice or boiled extract of Mimosa catechu). Catechins are found in green tea more than black tea. Polyphenolic catechins are the most common antioxidants that play an important role in preventing diseases such as cancers by preventing the formation of radicals which in turn leads to free radical-induced tissue damage (6). As discovered, EGCG, EGC, and ECG are the most important metabolites of catechins, which are produced by metabolisms exerted on green tea in the gut by intestinal microbiota (7). The bioavailability of catechins in humans is less than 4%, so intact tea catechins are not absorbed by the body. Besides, these substances are metabolized by the intestinal microbiota after reaching the large intestine. Therefore, the intestinal microbiota plays a vital role in the production of catechin metabolites and increasing their bioavailability. Many barriers can interrupt the production, absorption, and bioavailability of catechin metabolites, most of which are chemical degradation, liver metabolism, intestinal microbiota composition, and membrane permeability (8). It was determined in a study that fecal-derived catechin metabolites that are produced by intestinal microbiota, have been involved in regulating cancer pathogenesis (9, 10).
Retail Availability and Characteristics of Addictive Areca Nut Products in a US Metropolis
Published in Journal of Psychoactive Drugs, 2021
Whole ANs were available in two types––those stated for worship purposes only and the others that could be used for consumption. The nut packets from the two stores, where team members were asked if they would be needing them for worship or consumption, were the same brand and not labeled as AN on the packet, but as “Pooja Nuts (Black)” and contained the warning “For Religious Purpose Only. Not for Human Consumption.” The other whole betel nuts that were for consumption either were sold individually, or came in prepackaged plastic packets (typically six or more nuts per package). Processed ANs were available as slivers or chopped pieces or slices. The packages for these varied in weight and some of them also contained catechu, an extract of acacia trees that is not related to the areca palm but has various therapeutic effects (Ray, Sharatchandra, and Thokchom 2006). All these packages were clear plastic packets, none of which contained a label. The products stocked on the mouth fresheners’ shelf contained varying amounts of fennel seeds, AN slivers, or pieces and/or betel leaves along with flavoring agents, packaged in plastic bottle like containers. All of these items were labeled as mouth fresheners. Not all items found on this rack were AN products, but approximately 60% of them contained fennel seeds along with other ingredients. Items containing AN or betel leaves in any form were listed under ingredients on these containers.
