In the Caribbean, wild
spikenard was traditionally used as an
internal medicine to ease digestion and combat
nausea and flatulence. Externally, it is commonly
used as a mosquito repellent, because of its
strong aromatic smell.
In Africa, it is similarly used for stomach ache and colic as well as headaches and fever. It is also recorded as an antidote, as Sloane noted. It may also be given for colds and infections of the gall bladder and in baths to relieve pains and heal ulcers.
There is evidence that taking larger doses of this herb can lead to liver damage.
Wild spikenard comes from the warm and tropical Americas, but is now very widespread. In many places itís a problem weed, as it thrives in open places and can form dense thickets that smother the land and stop forests regenerating. Itís typically found along river banks, roadsides, in waste areas and clearings. Its spiny seeds spread very easily in water and attach themselves to fur, clothing and mud.
Extracts from the plant are said to have antibacterial and anti-fungal properties, and may contain potential anti-cancer agents. Some records say it can act as a contraceptive by blocking a fertilised egg from implanting in the womb.
