Herbs With High Linalool Concentration
Linalool is a naturally occurring terpene alcohol found in a wide variety of plants and fungi. Its pleasant, floral scent with spicy undertones is a signature component in many perfumed products and flavorings. However, beyond its aroma, linalool offers several potential therapeutic benefits, including anti-anxiety, sedative, anti-inflammatory, and antimicrobial properties. The concentration of linalool can vary depending on the plant species, growing conditions, and extraction methods. Here is a closer look at some of the top herbal sources.
Lavender (Lavandula angustifolia)
Lavender is arguably the most famous herb associated with linalool. The "true lavender," or Lavandula angustifolia, is particularly prized for its high levels of linalool and linalyl acetate, which give it its characteristic fresh, floral aroma. This is why lavender is a cornerstone of aromatherapy, frequently used to promote relaxation, reduce anxiety, and improve sleep quality. Inhalation of lavender oil has a long history of use for its calming effects. For internal use, lavender essential oil in capsule form has also been studied for its effectiveness in treating anxiety.
Coriander (Coriandrum sativum)
While many people associate coriander with the fresh, citrusy flavor of cilantro, the seeds of the coriander plant are a powerhouse of linalool. Coriander seed essential oil is typically composed of over 60% linalool, making it an extremely rich source. The two main enantiomeric forms of linalool are found in nature: (R)-(-)-linalool and (S)-(+)-linalool. Coriander is particularly rich in the (S)-(+)-linalool variant, also known as coriandrol. Its essential oil has shown strong antimicrobial and antioxidant properties. In traditional medicine, coriander seed preparations have been used for digestive complaints and anxiety.
Sweet Basil (Ocimum basilicum)
Different chemotypes of basil exist, but sweet basil (ct. linalool) is specifically cultivated for its high linalool content. Its essential oil can contain between 60% and 75% linalool, making it a very potent source for therapeutic applications. Sweet basil's warm, herbaceous, and slightly spicy aroma is a common feature in culinary dishes and is also harnessed in aromatherapy. The linalool in sweet basil is used to help ease tension and stress, calm the nervous system, and even act as a natural insect repellent.
Clary Sage (Salvia sclarea)
Clary sage is another significant source of linalool, with its essential oil containing both linalool and its ester, linalyl acetate. Its aroma is sweet, green, and floral with woody undertones. The composition of clary sage essential oil can vary, but it is reliably rich in these compounds, contributing to its relaxing and uplifting properties. Clary sage is a well-regarded herb in aromatherapy for its ability to reduce anxiety and act as a mood enhancer.
Other Notable Sources
Beyond these well-known examples, other herbs and plants also contain significant amounts of linalool. These include:
- Rosewood: A classic source, although its use is restricted due to sustainability concerns.
- Thyme: Contains linalool, especially certain chemotypes.
- Mint: A common herb with varying levels of linalool.
- Bergamot: The citrus fruit oil is a prominent source of linalool.
- Cinnamon: Found in smaller concentrations.
- Jasmine: Valued for its floral scent, which includes linalool.
