Allspice Side Effects and Benefits
|
Ground allspice is not, as some people believe, a mixture of spices.
Rather, it is the dried fruit of the Pimenta dioica plant. Pimenta dioica is
a tree natie to the West Indies, southern Mexico and Central America.
Allspice is also called Jamaica pepper, Kurundu, Myrtle pepper, pimento
and newspice.
Health Benefits of Allspice
Japanese researchers, Osaka City University, discovered three new
galloylglycosides; and the radical-scavenging activity nearly equivalent
to that of gallic acid (4) against 1,1-diphenyl-2-picrylhydrazyl radical. [3]
Later, different research groups reported that allspice contains
chemicals which have radical-scavenging and anti-cancer cells activities.
[6-8] This particular properties of allspice ingredients contribute the
potential health benefits of allspice.
In 1997, researchers from Universidad de Costa Rica reported the
blood pressure lowering effect of allspice in anestehetized rats with
blood pressure in normal ranges. They also demonstrated the aqueous
extract had a stronger effect on blood pressure lowering in the rats. [1
,4] The same group also reported that intraperitoneal administration of
allspice extracts led to a depression of the central nervous system
(CNS) of the rats. They also noted the analgesic and hypothermic
effects of allspice. [5] However, when the rats were dosed with the
extracts only, the researchers could not observe the changes in the
blood pressure, heart rate and body weight of the rats. [2]
In 2005, researchers from Mahatma Gandhi University, Kottayam
demonstrated the anti-hyperlipidemic or fat-lowering effect of aqueous
extract of Pimenta officinalis on experimental rats fed with high fat diet.
[9]
The scientific evidence for these health claims is very limited. In fact,
side effect such as allergic contact dermatitis has been reported. [10]
