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
Allspice may benefit people at risk of cancers
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.  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.
Allspice may have benefits of blood pressure lowering effects
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.  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. 
Allspice may have benefit on high lipid conditions
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. 
A study has showed the antimicrobial activities of allspice.

The scientific evidence for these health claims is very limited. In fact, side effect such as
allergic contact dermatitis has been reported.
