However, liquorice root has been linked to high blood pressure – an association that has prompted health bodies to issue a warning to prospective consumers.
US-based health body National Center for Complimentary and Integrative Health (NCCIH) says: “Although licorice root is generally considered safe as a food ingredient, it can cause serious side effects, including increased blood pressure and decreased potassium levels, when consumed in large amounts or for long periods of time.
“Because the composition of licorice products varies, it isn’t possible to definitely say that a particular level of intake is safe or unsafe.
“The effects of licorice on potassium and blood pressure are a particular concern for people with hypertension (high blood pressure) or heart or kidney disease.”
