Insights
Star anise infusions, used for infant colic, can cause serious neurological and gastrointestinal issues in babies due to potent neurotoxins. Regulation of these herbal products is crucial to prevent infant poisoning.
Area of Science:
- Toxicology
- Pediatrics
- Pharmacology
Background:
- Star anise infusions are culturally used for infant colic treatment.
- Concerns exist regarding the potential toxicity of star anise.
Observation:
- Several infant cases with neurological and gastrointestinal symptoms linked to star anise ingestion were reported in Spain.
- A 1-month-old infant experienced convulsive status after consuming star anise for colic.
Findings:
- The infant's seizures were controlled with diazepam, but symptoms resolved without anticonvulsant therapy.
- Clinical symptoms were attributed to star anise ingestion, containing neurotoxins like veranisatins.
- No underlying abnormalities were found in the infant.
Implications:
- Star anise contains potent neurotoxins, posing risks to infants.
- There is a need for regulation of natural products with pharmacological effects sold in pharmacies.
- Spanish Ministry of Health regulations in 2001 led to the withdrawal of anise-containing products.
Abstract:
Despite its potential toxicity, the use of star anise infusions for the treatment of infant colic is firmly rooted in our culture. In the last year, several cases of infants with acute neurological and gastrointestinal symptoms related to the ingestion of large quantities of star-shaped anise have been reported in Spain. We report a 1-month old girl who was admitted to our emergency room with convulsive status after ingesting a considerable amount of star anis administered to relieve possible infant colic. The patient required three repeat doses of diazepam to control the seizures. Because no abnormalities were found and outcome was favorable without anticonvulsant therapy, the clinical symptoms can be attributed to star anise ingestion, which contains potent neurotoxins such as veranisatins. The etiopathogenesis of this process and star anise toxicity are discussed and the need for the regulation of natural products with pharmacological effects which are freely dispensed from drug stores is stressed. Finally, the regulations of the Ministry of Health and Consumption for 2001 concerning the withdrawal of all anise-containing products are presented.

Seizures: Classification
Seizures are typically classified into two main categories: focal and generalized seizures.
Focal Seizures
Focal seizures originate from specific regions of the brain. These seizures are further sub-classified into two types:
