Its shape is oval, membranous, strong, arched; petiole is 1.5 cm long; glitters are 3-6 cm in diameter; blunt at base, usually equal or painful; 10-14 pairs are healthy, mutual and sessile. Oval or ovaloval its seeds are light brown, 1-2 cm long, linear or oblong, concave, and have a long coma. They taste bitter [6].

Origin and Distribution

This plant is common in India, especially in the Himalayas. HA has a traditional use and legend in India. In the Indian state of Odisha, the leaves of this plant are served with rice during the Nabanna festival [6]. This plant is found in tropical and subtropical regions of Asia and Africa. The tree grows in Myanmar, Sri Lanka and Pakistan, Nepal and Africa and blooms from May to July. In India it is found throughout the country, especially in the deciduous forests of the tropical Himalayas, at an altitude of 900-1250m [7] Chemical Constituents It is reported that the hard stem and seeds of this plant contain many steroid alkaloids such as canavanine, 3-aminocanavanine, 20-aminocanavanine, 3-aminopregnane and 3,20-diaminopregnane and their derivatives. A new steroid alkaloid called Holadysenterine has been isolated and characterized. It is based on the molecular formula C23H38N2O3 [8]. The root bark of Holarrina anti- dysenterica also contains conessin (C24H40N2), isokonessin (C24H40N2), conesimin/isokonessimin (C23H38N2), conarrhimin (C21H34N2) [9].

Mechanism of Action

Anti-dysenteric sea urchin extract causes intestinal stimulation by activating histamine receptors and relaxes the intestinal tract by blocking Ca2+ ion channels, thus reducing diarrhea [11]. Ethanol extract of the seeds causes an increase in dry stool and a decrease in stool retention [12]. Antioxidant properties- The antioxidant properties of H. anti-dysenterica indicate that the methanolic leaf extract scavenges superoxide ions and hydroxyl ions and reduces the ability to convert Fe3 to Fe2 10.

Pharmacological Activities: Anti-amnesic activity Application of the ethanolic extract of dysentery-resistant Hora Rayna seeds to various STZ groups for 28 days reduced AChE levels and prevented the increase in MDA levels and GSH depletion in a dose-dependent manner compared to the disease [12]. Cholinergic dysfunction is assessed by acetylcholinesterase activity. Decrease in AChE levels of MDA and Glutathione showed anti amensic property of Holarrhena anti-dysenterica. Neuroprotective Activity: MEHA treatment significantly prevents weight loss and lowers blood sugar and blood cholesterol levels relative to diabetes control, HbA1C level is considered an important indicator of AGEs, and available studies show that MEHA treatment significantly affects HbA1c levels. MEHA-treated mice showed improved locomotor performance compared to untreated mice, suggesting protection against diabetic neuropathy [13]. Acetylcholinesterase Inhibition b AChE microplate assay was performed on the anti-dysenteric alkaloid extract of Hora Reina seeds and showed 91% inhibition of anti-inflammatory acetylcholinesterase. Column chromatography of alkaloid extract on MCI-GEL using gradient weight system MeOH- H2O (50%, 60%, 70%, 80%, 90% (v/v) to obtain three fractions (Fr. 1) up to Fr. .3). The AChE inhibitory activity of these five compounds was tested by the Ellman method in 96-well microplates [14, 15]. Anti-diabetic Activity: HA ethanol extracts reduced blood glucose concentration within 1/2 hour after glucose administration in normoglycemic rats. Diabetic mice showed weight loss during the experiment. Weight gain was observed in rats in the diabetic group treated with Shigelladysenteriae and glibenclamide. Blood glucose levels as well as total cholesterol, triglycerides, AST, ALT, urea, and serum creatinine decreased in the ROM treatment group [16]. Methanolic extract of antidysenteric choleraema showed the same effect in diabetic rats. These restrictions indicate better metabolic control and stronger immunity [17] Hepatic glucose-6-phosphatase is an important enzyme in glucose homeostasis [18] and is negatively regulated by insulin [19]. After application of the aqueous extract, a significant improvement was noted in the biosensors, which may be due to the recovery of insulin [20]. Inhibiting intestinal α-glucosidase activity is an important strategy for controlling postprandial hyperglycemia in diabetes. Compared to the control group, the group administered acarbose or different doses of hydro-methanol extract showed a decrease in blood sugar results. Phenolic compounds and flavonoids in the extract are responsible for inhibiting α-glucosidase activity, thereby inhibiting glucose absorption content for postprandial hyperglycemia control [21]. Anti-urolithiasis Activity: In vitro studies have shown that HA crude extract can inhibit DPPH (2,2-diphenyl-1- picrylhydrazyl) free radicals, thus exerting antioxidant effects and inhibiting lipid peroxidation caused by rat kidney homogenate. Ha. Cr is not toxic to MDCK (kidney epithelial cell line) cells. In in vivo experiments, Ha.Cr had no significant effect on CaOx crystalluria. The stone- forming group lost weight compared to the saline group. Co- administration of Ha. Cr prevents weight loss. Co-application with Ha.Cr reduced polyurea and water uptake compared to conventional concrete. In lampreys, oxalate excretion increases while Ca++ excretion decreases. In histological studies, the number of CaOx crystal deposits was less in the Ha.Cr-treated group [22]. From this article it is suggested that the inhibitory effect of plant extracts on renal tubular CaOx crystal accumulation may be due to its antioxidant activity. These data therefore indicate that the protection of Holarrina anti-dysenterica in urolithiasis is mediated by different methods. Various articles have reviewed ulcerative colitis and bleeding hemorrhoids [23, 24]. Antibacterial Activity: The study for antibacterial activity was carried out by analyzing the millimeter inhibition zone or three bacteria (Staphylococcus aureus, Salmonella typhimurium and Escherichia coli). There was an inhibition zone of 10.05mm where the bark extract had the highest antibacterial activity against Staphylococcus aureus, while for Salmonella and E. coli this value was only 6.65mm and 2.7mm, respectively. Holarrena anti-dysenterica seed extract at 100% concentration also showed antibacterial activity against Staphylococcus aureus. Callus extract at 100% concentration showed a 4mm zone of inhibition against Staphylococcus aureus but little activity against E. coli. Many researchers have found that plant extracts have antibacterial properties in many ways [25, 26]. Anti-Inflammatory and Analgesic Activity: Methanol leaf extract of Holarrina anti-dysenterica with carrageenan showed inhibitory effect on paw edema in rats. Additionally, methanol extract of Holarrina antidysenterica inhibited the acetic acid-induced writhing response in a dose-dependent manner and exhibited an analgesic effect by improving tail beat latency [27]. An ethanol extract of Shigelladysenteriae exhibited analgesic effects by inhibiting the writhing response in albino mice [28]. Methanolic bark extract of Shigelladysenteriae showed decreased nitric oxide and malondialdehyde and increased superoxide dismutase and glutathione-Dinitrophenylsulfonic acid causes colitis in male albino Wilstar rats. Decreased nitric oxide levels suggest that decreased iNOS production may be responsible for the drug’s anti-inflammatory effects. H. Antidysenteric therapy also prevents goblet cell rupture, inflammatory cell infiltration, and inflammation of the mucosal layer [29]. Antimalarial Activity: H. conessin isolated from the root bark of anti-dysenterica showed the greatest anti-Plasmodial activity with a reproducible IC50 value of 1.3μg/ml in in vitro experiments and in vivo experiment at 10°C. It can prevent parasitemia increased by 88.95% mg/kg. It has also been shown to be related to conesin cytotoxicity in liver function tests. The liver is the most affected organ in the early stages of malaria, causing significant changes in host hepatocyte physiology and morphology. Increased alkaline phosphatase (ALP) and bilirubin levels indicate malaria-induced damage to liver cells. Increased ALP and bilirubin levels decreased at the 30mg/k dose [30]. The bark extract of H. anti-dysenterica has significant in vitro and in vivo effects on albino mice infected with Plasmodium falciparum and Plasmodium berghei. Chloroform extract showed antiplasmodial activity with IC50 values.

Uses of H. Anti-dysentery

Anti-dysentery is used in both Ayurveda and traditional Chinese medicine. Its seeds are used to treat diseases. Its bark has anti-inflammatory properties [31] In Ayurvedic medicine, it is used to treat anemia, jaundice, dysentery, stomach ache, diarrhea, epilepsy and cholera. It is widely used in the treatment of Asra (blood or blood diseases), Atisara (diarrhea), Kustha (leprosy), Pravahika (amebiasis) and Jwaratisara (diarrhea). Bark The bark is widely used in Ayurvedic medicine for the treatment of hemorrhoids, diarrhea, leprosy, bile and spleen diseases. The bark is used to treat menorrhagia, hemorrhoids and headaches. In Unani medicine, its bark is used to treat malaria, chest pain, asthma, bronchopneumonia, stomach problems, indigestion, diarrhea and dysentery [32]. Konessin is a steroid alkaloid extracted from the bark of Shigelladysenteriae and has significant antiviral activity with low cytotoxicity. Shigelladysenteriae has in vitro antimalarial activity against Plasmodium falciparum chloroquine with an IC50 of 5.5g/ml. The bark helps detoxify the blood.
