Geographical Distributions

Holarrhena pubescens is native in Tropical Africa, India, Burma (Myanmar), Indo-China, southern China (Yunnan) and Thailand. [4]

Botanical Description

H. pubescens is a member of the Apocynaceae family. It is a small deciduous tree that reaches up to 6 m high. The bark is grey, exfoliating and smooth outward and exudes abundant white latex in all parts. The leaves are opposite ovate-oblong with entire margins and pale-green in colour. The leaves measure 1.5-20 cm x 1.5-11 cm with cuneate or rounded base and apex acuminate to acute, shortly hairy to glabrous. The veins are pinnate with 5-25 pairs of lateral veins. The stipules are obscure. The petiole is 1 cm long, shortly hairy and glandular at base. The flowers are white and fragrant. Fruits are 30 cm long and appear in pairs, cylindrical, dark grey with white specks all over. The seeds are 1 cm long with 2-2.5 cm long hair at the top. [3][5]

Chemical Constituent

H. pubescens has been reported to contain antidysentericine, conarrhimin, conamine, conesimine, conessine, conimine, conkurchine, holadysenterine, holamine, holantosines A and B, holaphylline holaphyllamine, holarrenine, holarrhemine, holarrhimine, holarrhine, holarrhinine, isoconessimine, kuchicine, kurchamine, kurchessine, kurchine, kurcholessine, lettocine, norconnesine. [3][5][6][7] [8].

Plant Part Used

Bark and seeds [5].

Traditional Use

Barks are considered astringent, anthelmintic, stomachic, febrifuge, bitter, antidysenteric, and tonic [3][9]. The bark has been used to treat amoebic dysentery, piles, anaemia, asthma, bronchopneumonia, dropsy, dysuria, influenza, rheumatism, toothache, vomiting, nausea, intestinal worms, dyspepsia, chest complains and skin and spleen diseases [5]. Barks of the stem and roots can be administered orally to treat amoebic dysentery while a hot decoction of the stem bark is gargled to treat toothache [3]. The fresh bark was suggested to be used to treat acute dysentery [10]. Leaves pounded in water are used by Kenyans to treat stomachache [3].

Seeds of H. antidysenterica are considered cooling, astringent, febrifuge, digestive, bitter, carminative, antidysenteric, antiperiodic, aphrodisiac, expectorant, conceptive, anthelmitic and antidote to poison [5] [9]. The seeds can be used as antiperiodic when combine with other antiperiodic such as Cocculus cordifolius. Apart from that, Arabic and Persian writers considered the seeds as lithontriptic, aphrodisiac and tonic [9].

Roots boiled in milkare used as an antidote to snakebite and to treat venereal diseases. Infusion of the roots is used to stimulate milk production. In southern Africa, the infusion of the powdered roots is prescribed for constipation, abdominal pains, asthma, infertility, aphrodisiac, and to induce abortion [3]. The powdered roots and leaves are used to arrest post-partum bleeding and nose bleeding. In India the bark and leaves are topically applied over piles, scabies, boils and ulcers [3].

Preclinical Data


Anti-urolithic activity

The crude aqueos-methanolic extract of H. antidysenterica (0.3 mg/mL) was found to have ability to decrease the size of crystals of calcium oxalate monohydrate (COM) and transformed it to calcium oxalate dehydrate (COD) by significantly (p < 0.05) reducing the cell toxicity and LDH release in renal epithelial cells (MDCK) exposed to oxalate (0.5 mM) and COM (66 μg/cm (2)) crystals. The same extract (30-100 mg/kg) prevented toxic changes in male Wistar rats given lithogenic agents (ethylene glycol 0.75 % and ammonium chloride 1) for 21 days.  The antilitholithic activity is probably due to anti-aggregation and renal epithelial cell protective activity it may possessed. [11]

Antidiarrhoeal activity

Hydro-ethanol crude extract of H. antidysenterica (0.01-3.0 mg/mL) studies on the antidiarrhoeal activity of the plant proved to be positive as having gut stimulant and relaxant activities. The extract was found to initially stimulate smooth muscle contractions at low dose and cause relaxation at a higher concentration. It was found to inhibit high K+-induced contraction at concentration range of 0.01-1.0 mg/mL and shifted Ca++ concentration response curves to the right. The implication is that this is possibly mediated through activation of histamine receptors and Ca++ channel blockade. [12]

Antidiabetic activity

Hydro-methanol (2:3) extract of H. antidysenterica seeds (200, 400 and 800 mg/kg) administered orally to starch (6 g/kg) treated rats showed antidiabetic activity by significantly (p <0.05) reduced the blood glucose level with no significant variation compared to control group treated with only starch in isotonic saline solution for 400 and 800 mg/kg extract. The extract also inhibit the intestinal α-glucosidase rat intestinal supernatant in a dose dependent manner (IC50 0.52 mg/mL) compared to standard acarbose [13].

Immunomodulatory activity

H. antidysenterica was found to have the ability to stimulate phagocytic function and inhibit humoral component of the immune system [14].

Antimicrobial activity

Antibacterial activity

The crude methanol extract of the bark of H. antidysenterica was active against Staphylococcus aureus, S. epidermidis, Streptococcus faecalis, Bacillus subtilis, Escherichia coli and Pseudomonas aeruginosa. Chemical fractionation indicated the alkaloid portion was the most active against the bacteria especially S. aureus. There is also evidence that the ethanolic extract of the bark is effective against anti-methicillin-resistant S. aureus (MRSA) and extended spectrum beta-lactamases (ESbetaL)-producing E.coli. [15][16] [17][18][19][20][21].

Antimalarial activity

Chloroform extract of H. antidysensterica showed in vitro antiplasmodial activity (IC50 5.5 μg/mL) using pLDH assay and ED50 value 18.29 mg/kg in Plasmodium berghei NK65 stain infected Swiss albino mice. The extract (30 mg/kg) also significantly reduced the parasitaemia in mice by 73.2 %. [22]

Anticholinesterase activity

Five steroidal alkaloids were found to have anticholinesterase activity (conessine, conessimin, conarrhimin and conimin) with the most potent is conessimin with an IC50 value 4 μM  [6].


In screening of 50 medicinal plants for the content of pyrrolizidine alkaloids, H. antidysenterica was amongst the 3 species that showed positive presence of the compounds. Rats fed with H. antidysenterica showed evidences of liver toxicity which are disruption of the centrilobular veins, congestion or haemorrhage in the centrilobular sinusoids, centrilobular or focal hepatocellular necrosis compatible with the action of pyrrolizidine alkaloids. [23]

Clinical Data

Clinical findings

40 cases of amoebiasis and/or giardiasis were treated with H. antidysenterica bark extract. 70% of the cases that showed good response were Entamoeba histolytica cyst passers [24].

Pregnancy/Breast Feeding

No studies had been done on its abortifacient activity. The fact that it had been used to procure abortion in some African society, warrants a cautionary note on its use during pregnancy. However, there should not be any problem of its use during lactation being a lactagogue itself [3][5][9].

Interaction & Depletion

No documentation

Interaction with drug

The antidiabetic activity found in the plant makes it unsuitable to be used with antidiabetic drugs [13].
