The Lowdown on Sassafras Oil

Sassafras oil is an essential oil sourced from the sassafras tree. Safrole, its active ingredient, is used in the production of the drug MDMA (more widely known as "ecstasy"). Although sassafras oil was once widely used as a fragrance and flavoring agent, safrole is now recognized as a carcinogen (i.e., a cancer-causing agent).

The United States and Canada have banned sassafras oil (other than trace amounts of safrole) from foods and medications since 1960.

It should not be consumed orally (even small amounts can be fatal) or used externally.

Uses for Sassafras Oil

When applied to the skin, sassafras oil is said to treat head lice. However, there's a lack of scientific support for the claim that sassafras oil is effective as a head-lice treatment. Do not use it for head lice, as it can have serious health consequences even when used externally.

If you're seeking a natural remedy for head lice, there's some evidence that shampoo containing neem (an herb used in ayurvedic medicine) may be helpful. In addition, a number of essential oils (including tea tree, peppermint, lavender, and eucalyptus oils) have been found to destroy head lice in laboratory experiments. However, more research is needed before any of these remedies can be recommended in the treatment of head lice.

The Safety of Sassafras

Sassafras root bark and oil contain compounds (including safrole) that are carcinogenic.

 Even safrole-free sassafras has been linked to tumors. In addition to acting as a carcinogen, sassafras oil may have a number of toxic effects when consumed. Symptoms of sassafras oil toxicity include: abdominal pain, diarrhea, dizziness, hallucinations, low blood pressure, nausea, rapid breathing, rapid heartbeat, shallow breathing, and vomiting.

Use of sassafras oil is also associated with liver damage. What's more, there's concern that consumption of sassafras oil during pregnancy can result in miscarriage.

Like other essential oils, sassafras oil applied topically is absorbed through the skin. You can learn about the safety of other essential oils here.

If you're considering using sassafras (or any form of alternative medicine), it's crucial that you talk with your doctor first. Self-treating and avoiding or delaying conventional care may have serious consequences.

Sassafras Tea

Sassafras tea (a beverage made from the roots of the sassafras tree) is sometimes touted as a natural remedy for a broad range of health conditions (including bronchitis, the common cold, the flu, arthritis, eczema, psoriasis, and high blood pressure). Also said to "purify the blood," sassafras tea contains a considerable amount of safrole.

Due to safrole's potentially toxic effects, consumption of sassafras tea is not recommended. Adverse effects associated with the consumption of sassafras tea include itchiness, confusion, inflammation of the skin, vomiting, and difficulty breathing.

While it's possible to purchase sassafras tea products from which the safrole has been removed during production, it might be wise to avoid sassafras entirely due to the potential toxicity.

Instead, many other teas may offer health-enhancing benefits and aid in the treatment of certain health issues. For instance, studies show that green tea may help lower your cholesterol, preserve brain health, and strengthen bones to fight off osteoporosis.

A type of herbal tea, hibiscus tea shows promise as a natural means of controlling blood pressure and cholesterol. Black tea, meanwhile, may help fight diabetes and protect against heart disease. And rooibos (a tea made from the South African plant Aspalathus linearis) may have some beneficial effects on the immune system.

Environmental Concerns

Production of sassafras oil is contributing to the destruction of rare trees in southwest Cambodia, according to the nonprofit conservation group Fauna & Flora International (FFI). In 2009, FFI partnered with the Cambodian Ministry of Environment to identify, raid, and shut down two illegal sassafras oil factories in the Cardamom Mountains of Cambodia. The FFI states that sassafras oil production not only harms the trees themselves, but causes significant damage to the entire forest ecosystem.
