Is Lavender Dangerous?

Cultivation

• Plant container-grown specimens in the early spring. Set plants in a sunny location, leaving 2 to 3 feet of space between shrubs. Take care to not over-water lavender plants; they are highly drought-resistant and do not respond well to wet conditions. Harvest flower stalks just before they reach full bloom, cutting the stems near the base of the plant. Gather the stalks into a bundle, then hang them bloom-side down in a dark, dry location. Wait 3 to 5 weeks, then trim the stalks, remove the dried foliage and use as desired. Those who have sensitive skin or allergies may want to wear gloves when handling the plants. Though not highly irritating, the oils from the lavender plant can cause itchiness for those who are sensitive to it.

Topical Applications

• The aroma of lavender is said to have soothing, calming, naturally restorative properties. As a result, lavender extracts are commonly included in lotions, soaps, bath salts and body oils. For many people this poses no problem; however, according to a 2007 report from the National Institutes of Health, the use of products containing lavender can lead to breast development in young boys. Chemical compounds found in the plant materials imitate the female hormone estrogen while repressing the production of the male hormone androgen, leading to the development of breast tissue.

Ingestion

• Though lavender blossoms and oils work best when used in decorative displays or for aromatic purposes, it is not uncommon for the flowers to be used in oral extracts or teas. These brews should be consumed with caution. The National Center for Complementary and Alternative Medicine includes lavender on their list of toxic compounds. Consumption of lavender extracts can lead to headaches, digestive upset and constipation. Additionally, ingesting lavender can interfere with prescription medications or cause unwanted drowsiness.

Essential Oil

• Lavender essential oil is more powerful than the plant itself. Unlike fresh plants, the extracts are concentrated and extremely strong. Like all essential oils, lavender oil should be diluted before use. Applying lavender essential oil directly to the skin can lead to irritation and redness. Should this happen, wash the affected area with soap and water. Do not rub the oil into the skin. According to research done by the National Association for Holistic Aromatherapy, the compounds found in lavender oil can be absorbed by the skin and taken up by the bloodstream.
