Calamus Essential Oil: A Traditional Remedy 

Botanical Name: Acorus calamus

Extraction Method: Steam Distillation (from fresh or dried, unpeeled roots)

Source: Roots of the Calamus plant, a reddish aquatic plant with sword-shaped leaves and small greenish-yellow flowers. All parts of the plant possess a distinct, pleasant fragrance.

Aroma: Warm, spicy, and slightly sweet.

Key Chemical Constituents: Calamus oil's composition varies depending on the variety and origin of the plant. It can contain significant amounts of β-asarone, which has raised safety concerns (see below). Other constituents may include α-asarone, eugenol, and other volatile compounds. Note: The presence and concentration of asarones are crucial for determining the safety of this oil.

Properties and Traditional Uses:

Calamus has a long history of use in traditional medicine systems. Historically, it has been used for various purposes, including:

• Digestive Support: May have carminative properties.
• Respiratory Support: Traditionally used for coughs and congestion.
• Nervine: Historically used for its calming effects.

Potential Benefits (Further research is limited and needed):

• It is crucial to understand that due to the potential presence of β-asarone, the use of Calamus oil is highly restricted in many countries. Traditional uses do not negate the potential risks.

Safety Information - EXTREME CAUTION IS ADVISED:

• Asarone Content: The presence of β-asarone in some varieties of Calamus is a major safety concern. β-asarone is carcinogenic and neurotoxic in animal studies. Therefore, Calamus oil containing significant levels of β-asarone should be avoided. It is essential to know the chemotype of the oil you are using.
• Restricted Use: Due to the potential toxicity of β-asarone, the sale and use of Calamus oil are restricted or banned in many countries.
• Dilution is Essential (if using a safe chemotype): If you are using a Calamus oil that is certified to be low in or free of β-asarone, it must always be diluted with a carrier oil before topical application. Even then, use it with extreme caution.
• Patch Test: Even with a low-asarone chemotype, a patch test is mandatory before using the oil.
• Pregnancy and Breastfeeding: Do not use Calamus oil if you are pregnant or breastfeeding.
• Children and Pets: Do not use Calamus oil on children or pets.
• Internal Use: Do not ingest Calamus oil under any circumstances.
• Eye Contact: Avoid contact with eyes. If contact occurs, rinse thoroughly with water.
• Medical Conditions: If you have any underlying health conditions, including epilepsy, heart problems, kidney problems, or any other serious medical condition, do not use Calamus oil unless under the direct supervision of a qualified and experienced aromatherapist and physician.
• Storage: Store in a cool, dark place, away from heat and direct sunlight. Keep the bottle tightly closed.
• Flammability: Keep away from open flames and ignition sources.
