General Information


Antiaris toxicaria is a member of the Moraceae family. It can reach up to over 40 m height. The leaves are deciduous, oblong-oval, sometimes approaching ovate, shortly acuminate, entire, downy, and reticulated especially beneath where they are slightly ferruginous with the nerves prominent. The measurement is from 7.5-12.5 cm long with the base slightly cordate and oblique. The flowers are monoecious and axillary. The fruit is pear-shaped, pulpy, measure 1-1.25 cm wide and black when ripe. [19]

Plant Part Used

Seeds, stems, barks, latex.

Chemical Constituents

Toxic glycoside, cardiac glycoside α-, ß- and γ- antiarin, antiarol (3,4,5-trimethoxyphenol), fats, α-amyrin cinnamate, α-amyrin stearate, and a number of cardenolides.[1] 

Antiarol, potassium nitrate, antiaresin, crystalline protein, toxicarina, malayoside, periplorhamnoside, cymarol, convallotoxin, desglucocheirotoxin, strophalloside, antiogoside, antioside, a-antioside, strophanthojavoside, antialloside. [3] [5]

Traditional Uses

The latex of the A. toxicaria formed the main ingredient in the poison for the tips of arrows and darts used by the jungle tribes for hunting. Surprisingly, this latex is used by some African tribes to treat wound and skin complaints such as eczema and leprosy, while it is commonly known that the latex can cause fatal when escaping into general circulation. Che Wong Tribe of Lanchang Pahang used a few drop of A. toxicaria intoxication as instant remedy at the infected wound. [2][7] The small quantity of latex act as mild cardiac and circulatory stimulant by which the action is similar with digitalis.[4] [6] It also stimulates intestinal and uterine contraction. [6]

The treated bark of A. toxicaria is used to treat diseases like fever, pain, worm infestations and hepatitits. [2] The decoction of the bark is used by Fijians as children’s tonic. [1]

The seeds are bitter and are used by the Indians as febrifuge and remedy for dysentery. [4]

Preclinical Data


Positive inotropic activity
The sap extract of A.toxicaria was found to inhibit the Na+, K+-ATPase activity in guinea pig heart muscle. The frog’s heart also observed there was a fall in twitch tension after the increased tension on mechanograms. This is indicative of the presence of cardiac glycosides in the sap extract. [8] Some of the cardenolides gylcosides which could be responsible for these activities in the sap extracts had recently been identified and their structures determined. It is including of 12-ß-hydroxycannogenin-3-ß-O-ß-D-deoxygulopyranoside, 3-ß-O-α-L-rhamnopyranoside, Toxicarioside D, antiarioside A-I, antiarotoxinin, malayoside. Studies comparing their positive inotropic action against those of ouabain had shown that malayoside was nearly equipotent. [9] [10] [11] 

Cytotoxic activity
A number of the cardinolide glycosides isolated from various parts of A. toxicaria were found to have cytotoxic activities. Toxicarioside F, G and  H showed significant cytotoxic activity against chronic myelogenous leukemia (K562), human gastric (SGC-7901), human hepatoma (SMMC-7721) and HeLa cell lines in vitro by the MTT method. From the seeds of A. toxicaria, toxicarioside J, K and L, and 7-drimen-3b,11-diol3-O-b-d-dlucopyranoside were isolated and they were active against SGC-7901 and SMMC-7721 cell lines. [12] [13] [14] [15]

Osteoblastic stimulation activity
A 19 phenylpropanoid and lignin derivatives were isolated from the stem of A. toxicaria. The screening results showed that at concentration 10-8 M, the benzofuran lignans significantly stimulate the proliferation of UMR 106 cells, while certain cells could enhance alkaline phosphatase activity. [16]

Endoglin/TGF-b signalling inhibition activity
Toxicarioside A, is amongst the compounds isolated from A. toxicaria was found to be able to influence bone marrow stromal HS-5’s function and inhibit HS-5 cell proliferation by altering endoglin-related ALK1 (Smad1) and ALK5 (Smad2) signalling. [17]


The extract of A. toxicaria is poisonous and has been used since antiquity as a poison arrow and blow pipe darts by people of the rainforest. It is also used in criminal acts in which the extract of A. toxicaria is used to be put into wells to poison families. The toxicity of the sap is probably due to the presence of high levels of cardiac glycosides in particular α and ß antiarin. Death ensues within 15 minutes in humans due to cardiac arrest. This is normally preceded with vomiting and convulsion. [18]
