Petiveria alliacea, commonly known as Anamu, is a perennial shrub prevalent in South and Central America, some areas in Africa and southeastern United States. It has been widely used in folk medicine to treat inflammation, infection, and as an anticancer agent. Extracts of this herb demonstrated antimicrobial, antifungal (1) (2), antiviral (3), antiprotozoal (4), and immunomodulatory (5) properties in vitro. Data on its cytotoxic effects are conflicting (6) (7) (14).
The whole plant extracts also caused anxiolytic effects whereas an extract of aerial parts showed anxiogenic properties (15); the root extracts showed anticonvulsant effects in mice (16).
Although Petiveria extract exhibited anti-inflammatory and analgesic effects in animals (8), it did not show any benefits in patients with osteoarthritis when compared to placebo (9).
In vitro and in vivo assays showed that it also has mutagenic effects (11). More studies are needed to evaluate the traditional uses.
Dibenzyl trisulphide, one of the active ingredients of Petiveria alliacea, caused disassembly of microtubules in neuroblastoma cells resulting in inhibition of cell proliferation (12). Oral administration of a root extract of Petiveria alliacea to rats resulted in reduced migration of neutrophils, mononuclear cells and eosinophils to the site of inflammation, thereby exerting an anti-inflammatory effect (8). The root extract of Petiveria alliacea exhibited antimitotic effect in vivo (13) and extracts from its leaves and stems showed hypoglycemic effects in mice (10). The polysulphides of Petiveria alliacea were shown to have antifungal and antibacterial activities (1) (2). Methanolic extracts of Petiveria alliacea showed active inhibition of bovine viral diarrhea virus (BVDV) replication in vitro (3).
Petiveria alliacea may lower blood sugar level (10).
A small study of Petiveria alliacea did not find any benefit in patients with osteoarthritis. Clinical trials are needed to evaluate its health benefits.

BOTTOM LINE: Petiveria alliacea has not been shown to treat cancer in humans.
Petiveria alliacea (Anamu) is an herb found in South and Central America, some areas in Africa and southeastern United States. It has been widely used in folk medicine. Studies done in laboratories and in animals have shown that Petiveria alliacea can prevent certain infections, reduce inflammation and pain, and regulate cancer cell growth. However, this has not been confirmed in humans. A small study done in patients with osteoarthritis did not show benefits of Petiveria alliacea compared to placebo.
A small study of Petiveria alliacea did not find any benefit in patients with osteoarthritis. Clinical trials are needed to evaluate its health benefits.
