Index


Introduction

Petiveria alliacea (Family Phytolaccaceae), commonly known as anamu, is a herbaceous perennial. P. alliacea can be found in growing in tropical areas of Central and South American, the Caribbean, and Africa. The leaves and roots of the plant have a strong odor. An excellent source of information on this plant is presented on the Raintree Nutrition web site. The Raintree site includes ethnobotanical data, references, and abstracts. Some of the common names for Petiveria alliacea include:

A more complete list of common names can be found on the Raintree site.

Chemical Compounds and Nutritional Value

P. alliacea contains several biologically active compounds. The quantity of compounds varies in the plant parts. Primary compounds in the essential oil of the roots include: benzaldehyde, dibenzyl disulfide, dibenzyl trisulfide, and cis- and trans-stilbene. Some of the compounds in P. alliacea are listed below.

Toxicity

Few data on the toxicity of P. alliacea could be found in the literature. In one study with mice, oral doses did not cause toxicity. However, methanol extracts of the plant do cause uterus contractions, which can lead to abortion - one of its uses in traditional human medicine. Also, extracts have been shown to inhibit mitosis.

Caution should be taken if P. alliacea is fed to animals on a regular basis. The plant can accumulate nitrates and has caused nitrate poisoning in cattle. Also, in studies where cattle were fed P. alliacea regularly (3g/kg bodyweight/day), the cattle suffered several adverse reactions.

Uses and Efficacy

In the Dominican Republic, the roots of Petiveria alliacea are used in treatments for internal parasites in livestock and as an insect repellent. No studies on the anti-parasitic properties of P. alliacea in livestock could be found in the literature. However, when P. alliacea root was applied to soil, populations of Meloidogyne incognita were decreased compared to controls. Also, hexane extracts of the plant showed some activity against the blood protozoa Trypanosoma cruzi in vitro. Studies have shown that crude ethanol extracts exhibit some repellent activity against Boophilus microplus (tick species). Dibenzyltrisulfide, one of the compounds in the roots of P. alliacea, is insecticidal (Cylas formicarius elegantulus and Hypothenemus hampei) and acaricidal (Boophilus microplus).

In other studies, extracts of P. alliaceae: provided some protection against Listeria monocytogenes infections in mice, inhibited inflammation in induced paw oedema in mice, and reduced blood platelet aggragation in vitro.

P. alliacea has been used to treat the following ailments in humans:
