1. What is Sassafras?
Sassafras is a genus of three extant and one extinct species of deciduous trees in the family Lauraceae, native to eastern North America and East Asia. The North American species, Sassafras albidum, is the most well-known. It’s characterized by its unique leaves, which can appear in three different shapes on the same tree: oval, mitten-shaped (with one lobe), and three-lobed. The bark is thick, reddish-brown, and deeply furrowed. Sassafras trees produce small, yellowish flowers in the spring, followed by dark blue berries that are a favorite food source for birds.
Sassafras has a long history of use, both culinary and medicinal, by Native American tribes and later by European settlers. The root bark, in particular, was highly valued for its aromatic properties and purported health benefits. Today, sassafras is primarily used in the production of root beer (though safrole-free extracts are now used) and as a flavoring agent.

2. Historical Uses of Sassafras
Sassafras boasts a fascinating history, deeply intertwined with the traditions of Native American cultures and the early European settlers in North America. Native American tribes utilized sassafras for centuries, recognizing its medicinal properties and integrating it into their traditional healing practices. They employed various parts of the tree, including the root bark, leaves, and twigs, to address a wide array of ailments.
2.1. Native American Applications
Native Americans traditionally used sassafras as a remedy for various ailments. They prepared teas from the root bark to treat:
- Skin Conditions: Eczema, sores, and wounds.
- Digestive Issues: Stomach aches, diarrhea, and intestinal worms.
- Fever and Colds: As a diaphoretic (to induce sweating) and to relieve congestion.
- Rheumatism and Gout: To reduce inflammation and pain.
- Menstrual Problems: To regulate menstruation and ease cramps.
They also used the leaves as a poultice for wounds and the bark as a flavoring agent in food. Some tribes even used sassafras wood for constructing canoes and dwellings due to its durability and aromatic qualities.
2.2. European Colonists’ Adoption
When European colonists arrived in North America, they quickly learned about the uses of sassafras from the Native Americans. Sassafras became one of the first American products exported to Europe. It was highly valued for its perceived medicinal properties and was even touted as a cure for syphilis, plague, and other diseases.
Sassafras was in such high demand that it played a significant role in early colonial economies. Expeditions were organized solely for the purpose of collecting and exporting sassafras root. Its popularity eventually waned due to safety concerns related to safrole, a naturally occurring compound found in sassafras.
3. Chemical Composition of Sassafras
The chemical composition of sassafras is complex and includes various compounds, but the most notable and concerning is safrole. Safrole is an aromatic oil that gives sassafras its characteristic scent and flavor. However, safrole has been found to be carcinogenic and hepatotoxic, meaning it can cause cancer and liver damage.
3.1. Safrole Content and Regulations
Safrole content varies depending on the part of the tree and the method of extraction. The root bark contains the highest concentration of safrole, followed by the root oil. Due to its health risks, the U.S. Food and Drug Administration (FDA) banned the use of safrole as a food additive in 1960. However, sassafras extracts that have had the safrole removed are still permitted for use in flavoring.
3.2. Other Chemical Components
Besides safrole, sassafras contains other chemical components, including:
- Eugenol: An aromatic oil with antiseptic and anesthetic properties.
- Sesamin: A lignan with antioxidant and anti-inflammatory effects.
- Various Alkaloids: Which may contribute to its medicinal properties.
- Tannins: Which give it astringent properties.
While these other compounds may offer some potential benefits, the presence of safrole overshadows them due to its significant health risks.
4. Uses of Sassafras Today
Despite the concerns surrounding safrole, sassafras continues to be used in various ways today, albeit with regulations and precautions in place.
4.1. Culinary Applications (Safrole-Free)
The primary culinary use of sassafras today is in the production of root beer. However, commercially produced root beer must use safrole-free sassafras extract. This ensures that the beverage retains the characteristic flavor of sassafras without posing a health risk.
Creole cuisine also utilizes dried and ground sassafras leaves, known as filé powder, as a thickening agent and flavoring in dishes like gumbo. Filé powder provides a unique flavor and aroma to these traditional dishes.
4.2. Traditional Medicine (Limited and Cautious)
While sassafras was once widely used in traditional medicine, its use is now limited and approached with caution due to the risks associated with safrole. Some herbalists still use safrole-free sassafras extracts for various purposes, but it is crucial to consult with a qualified healthcare professional before using sassafras for medicinal purposes.
4.3. Other Uses
Sassafras oil, with safrole removed, is sometimes used in aromatherapy for its pleasant scent. The wood of the sassafras tree is also valued for its durability and resistance to decay, making it suitable for use in furniture and construction.
5. Potential Benefits of Sassafras (Safrole-Free)
While the presence of safrole raises significant concerns, some studies suggest that safrole-free sassafras extracts may offer potential health benefits. However, it is important to note that more research is needed to confirm these benefits and to fully understand the safety profile of safrole-free sassafras.
5.1. Antioxidant Properties
Sassafras contains antioxidants that may help protect against cell damage caused by free radicals. Antioxidants play a crucial role in maintaining overall health and preventing chronic diseases.
5.2. Anti-Inflammatory Effects
Some studies suggest that sassafras may possess anti-inflammatory properties, which could be beneficial in managing inflammatory conditions. Inflammation is linked to various health issues, and natural anti-inflammatory agents are of great interest.
5.3. Potential Insecticidal Properties
Sassafras oil has been shown to have insecticidal properties, making it a potential natural alternative to synthetic insecticides. This could be particularly useful in organic gardening and pest control.

6. Risks and Side Effects of Sassafras
The most significant risk associated with sassafras is its safrole content. Safrole has been shown to be carcinogenic and hepatotoxic in animal studies. The FDA has banned the use of safrole as a food additive due to these health concerns.
6.1. Cancer Risk
Safrole has been linked to an increased risk of liver cancer and other types of cancer. Even small amounts of safrole exposure over time can potentially increase cancer risk.
6.2. Liver Damage
Safrole can cause liver damage, leading to inflammation, cell damage, and impaired liver function. The liver plays a vital role in detoxification, and damage to the liver can have serious health consequences.
6.3. Other Side Effects
Other potential side effects of sassafras include:
- Sweating and Hot Flashes: Sassafras can cause increased sweating and hot flashes.
- Vomiting: High doses of sassafras can lead to vomiting.
- Increased Blood Pressure: Sassafras may elevate blood pressure.
- Hallucinations: In rare cases, sassafras has been associated with hallucinations.
- Skin Rashes: Topical application of sassafras can cause skin irritation and rashes.
Due to these risks, it is crucial to avoid using sassafras products that contain safrole.
7. Precautions When Using Sassafras
Given the potential risks associated with sassafras, it is essential to take certain precautions:
7.1. Avoid Safrole-Containing Products
Only use sassafras products that are certified as safrole-free. Check the product label carefully to ensure that it does not contain safrole.
7.2. Pregnancy and Breastfeeding

7.6. Consult a Healthcare Professional
Before using sassafras for any purpose, consult with a qualified healthcare professional to discuss the potential risks and benefits.
8. Sassafras and Drug Interactions
Sassafras can interact with certain medications, potentially leading to adverse effects.
8.1. Sedatives
