The FDA has issued a warning to consumers that a popular Morning Sickness remedy called Nzu has been found to contain high levels of lead and arsenic in a laboratory test. High levels of lead have been shown to have harmful side effects on a developing fetus’ brain and nervous system. Arsenic is a known carcinogen and long-term exposure has been linked to bladder, skin, and lung cancers.
Nzu is also called Calabash clay, Calabar stone, Mabele, Argile and La Craie. It generally resembles balls of clay or mud and is usually sold in small plastic bags with a handwritten label identifying it as “Nzu” or “Salted Nzu.”
