Self-applied Lavender oil improves daily life of patients with knee osteoarthritis

A 2018 randomized, single-blinded clinical trial investigated the effects of massage with a 3% dilution of Lavender oil on the ability of patients with knee osteoarthritis to perform normal daily activities.

The Iranian researchers divided 80 participants into three groups: aromatherapy massage (27), massage with almond oil (27), and no intervention (26). Patients in both of the massage groups performed a 20 minute self-administered effleurage three times a week for three weeks, after being instructed on the whole procedure. All participants received their usual pain medication.

The WOMAC score was measured, tracking the activities of daily living before the study, immediately following intervention, after 1 week and after 4 weeks. There was a significant improvement in both the Lavender massage and plain massage groups right after the intervention, compared to the third group, although the Lavender group showed greater improvement. After one week, only the Lavender group showed significant improvement. At the four weeks, all groups showed the same scores.

WOMAC is an osteoarthritis index that assesses pain (5 activities), stiffness (at two points in the day) and physical function (17 activities).

The researchers concluded that Lavender oil massage could temporarily improve the ability of patients with knee osteoarthritis to perform the activities of daily living. They surmised that the effect may be due to the calming effect of inhaling Lavender, its pharmacological properties (anti-inflammatory, analgesic), as well as the massage itself.

    Hello, if the dermal limit of Lavender E.O. is 1% maximum (unless I am reading the book on Essential Oil Safety wrong), how can 3% be used in a massage oil? I also followed your link to the pubmed article and I do not see the reference to the amount of Essential Oil used. Can you please clarify? Thank you

      Hi Katia, in Essential Oil Safety there is a dermal limit of 0.1% forLavender absolute (p326) but there is no limit for Lavender essential oil (p327, Safety Summary). Regarding the amount of Lavender oil used, the link is to be abstract, as the full article is not open access (i.e. free) and so we cannot provide a public link to it.
