Introduction
Star Anise (Illicium verum), known in India as Chakri Phool, is arguably the most aesthetically pleasing and pharmacologically powerful spice in Asian cuisine. It is the dried, star-shaped fruit of an evergreen tree native to China and Vietnam, prized for its potent, licorice-like aroma and warm, sweet flavor, which comes from the essential oil compound anethole.
Further, its culinary role in garam masala, biryanis, and aromatic broths like Vietnamese phở, its true international significance lies in its high concentration of shikimic acid, a compound necessary for manufacturing the antiviral drug Tamiflu (oseltamivir). It creates the spice, an essential resource for combating viral infections like influenza. At the same time, its rich profile of antioxidants and antimicrobial agents continues to be studied for advantages ranging from improved digestion to potential defense against certain bacteria and fungi.
Star Anise
Star anise (Illicium verum) is an evergreen shrub or smallish tree native to Asia. It’s traditionally utilized as a spice in food and also as a medication.
Star anise seeds contain chemicals that might have antibacterial effects. One such chemical is shikimic acid, which is utilized to make oseltamivir (Tamiflu), a flu remedy. However, it’s not clear if star anise itself has antiviral effects.
Individuals utilize this for respiratory infections, colic in babies, stomach disorders, and other conditions, but no good scientific evidence supports these benefits.
In 2003, the US FDA cautioned consumers not to consume teas brewed from star anise due to reports of heavy side effects. Some star anise tea products have been infected with Japanese star anise (Illicium anisatum), a known toxin.
What does star anise taste like
It has a bold, distinct, and highly aromatic flavor profile characterized by a rich licorice or anise note.
Here is a sensory breakdown:
- Primary Taste: Intensely sweet and licorice-like. This flavor comes from the compound anethole, which is present in high concentrations and is the same compound found in anise seed and fennel.
- Aroma and Warmth: It carries a pronounced warm, spicy, and woody aroma reminiscent of a mix between cinnamon, clove, and fennel. This warm, earthy quality deepens when the spice is used in slow cooking.
- Intensity: The flavor is potent and stronger than anise seed or fennel. Because of its intensity, star anise must be used sparingly; if too much is added, it can easily overpower a dish and leave a slightly medicinal or bitter aftertaste.
- Culinary Role: Its complex profile allows it to bridge the gap between sweet and savory; it is essential in savory Chinese braised meats and Vietnamese phở, yet equally at home in sweet applications like mulled wine, pies, and Indian masala chai.

Caution: Always use genuine Chinese Star Anise (Illicium verum). Never confuse it with the highly toxic Japanese Star Anise (Illicium anisatum), which looks similar but is poisonous. Avoid drinking star anise tea if you are pregnant, breastfeeding, or administering it to infants without medical guidance.
Side effects of star anise
While Chinese Star Anise (Illicium verum) is generally considered safe when used as a food spice, its consumption carries significant risks, particularly as a strong tea or supplement, mainly due to potential toxicity and adulteration.
The side effects of star anise are severe and centered mainly around the confusion with a toxic cousin:
1. High Risk of Toxicity (The Contamination Danger)
The most severe risk comes from contamination with Japanese Star Anise (Illicium anisatum), which looks nearly identical but is highly poisonous.
- Neurotoxicity: Ingestion of the toxic species can cause severe neurological symptoms, particularly in infants and children. These neurotoxic effects include:
- Seizures and Convulsions.
- Hallucinations and altered consciousness.
- Irritability, severe lethargy, and spasticity.
2. Gastrointestinal Distress
- Severe Nausea and Vomiting: Gastrointestinal symptoms are common in cases of toxicity or when excessive amounts of the spice are consumed, especially when brewed as a concentrated tea.
- Abdominal Cramping and Diarrhea: This can occur due to high concentrations of specific compounds.
3. Dosage and Population Sensitivity
- Unsafe for Infants and Children: Due to the severe risk of neurotoxicity from contamination, star anise tea is widely considered unsafe for infants and children. Case reports have linked its use (often as a home remedy for colic) to seizures in babies.
- High Dose Toxicity: Even pure Chinese star anise (Illicium verum) contains naturally occurring neurotoxic compounds (veranisatins) that can cause adverse impact if consumed in excessive quantities or if the tea is boiled for too long, leading to a high concentration.
4. Drug Interactions and Allergies
- Blood Thinners: Star anise contains compounds that might slow blood clotting. Due to the higher risk of bleeding or bruising, it should be used with caution and ideally avoided by individuals taking anticoagulant medications (blood thinners).
- Hormone-Sensitive Conditions: Due to its mild phytoestrogenic activity (mimicking estrogen), star anise might interfere with hormone therapies or worsen hormone-sensitive conditions like breast cancer.
- Hypersensitivity: Allergic reactions, including skin rashes and swelling, are possible in sensitive individuals.
Safety Precaution: To minimize risk, always buy whole star anise from a reputable source and use it sparingly in food. Avoid star anise teas if the purity of the source cannot be guaranteed.
