Toxicology Question of the Week
March 17, 2017
Is the shamrock toxic?
We boast of the green on our isle’s shores
Thanks to the plant that grows so grand.
It thrives in the mires, the bogs, and the mores.
The dear little Shamrock of Ireland.
As St. Patrick’s Day approaches, the world looks to celebrate the Irish culture with international festivals, parades, dancing, special foods, and the “wearing of the green”. One traditional symbol of St. Patrick’s Day is the Shamrock, which was chosen as Ireland’s national emblem based on legends of its use by St. Patrick. The Shamrock is a common name given to several different types of three-leafed clovers native to and plentiful in Ireland. Although most commonly associated with yellow clover or white clover, the exact type of plant that represents the “true” Shamrock remains a mystery. Several different varieties of clover exist in the United States. Some are native to the continent, while others have been naturalized to North America, originating in Europe and Asia. How harmful are the “Shamrocks” found in the USA? Should we be concerned for individuals who place sprigs of “Shamrocks” in their beverages and then drink a toast to this Irish holiday?
A brief overview of the potential toxic effects that could develop from the different genera of clover will best answer this question. Some of the common types of clover found in this country include:
Thus, based on this synopsis, severe toxicity from the ingestion of a small amount of clover residue that might be in a beverage is unlikely; however gastrointestinal upset could develop. Of course, if someone eats a large quantity of the more dangerous clover species, then serious side effects could arise. As always, please contact the poison control center for any questions or concerns that might surface during the St. Patrick’s Day festivities.
For each petal of the shamrock
This brings a wish your way
Good health, good luck, and happiness
For today and every day
