A number of essential oils, extracted from seeds or roots of certain plants have a number of beneficial uses in terms of the physical and physiological aspect of an individual. One such oil is the blackcurrant oil, which is extracted from the seeds of Ribes nigrum or the blackcurrant plant. Blackcurrants are round, blackish-purple colored berries that grow on thornless shrubs. Eating blackcurrants or including their extract is known to have a number of beneficial effects on the overall health of a person.

However, there are also a few side effects, owing to excess usage of this oil.
