| Medical Condition | Uses based on scientific evidence | Grade* |
| ankylosing spondylitis | early human studies have found conflicting results on the use of massage with lavender aromatherapy in this condition. there is not enough scientific evidence to recommend lavender aromatherapy for rheumatoid arthritis pain. | c |
| anxiety state unspecified | lavender aromatherapy is traditionally used for relaxation. it is reported to help relieve anxiety in several small studies, although negative results have also been reported. better research is needed before a strong recommendation can be made. | b |
| cervicalgia | early human studies indicate a potential role for lavender aromatherapy in combination with massage in the short-term treatment of neck pain. more studies are needed. | c |
| contact dermatitis and other eczema unspecified cause | in a small clinical trial, essential oils were used in combination with massage to treat childhood atopic eczema. it was found that there was deterioration in the patient's eczema, which may have been due to possible allergic contact dermatitis provoked by the essential oils themselves. more study on the effect of lavender essential oil alone is needed before any firm conclusions can be made. | d |
| dementia in conditions classified elsewhere without behavioral disturbance | small human trials looking at the effects of lavender aromatherapy on agitation and behavior in patients with alzheimer's dementia report conflicting results. better quality studies are needed before a firm conclusion can be drawn. | c |
| dementias | small trials investigating the effects of lavender aromatherapy on agitation and behavior in patients with alzheimer's dementia report conflicting results. further well-designed studies are needed before a conclusion can be drawn. | c |
| depressive disorder not elsewhere classified | preliminary research suggests that lavender may be helpful as an adjunct to prescription antidepressant medications. additional research is necessary before a firm conclusion can be drawn. | c |
| lumbago | early research suggests that the impression of pain intensity and unpleasantness may be reduced after treatment with lavender therapy. other research has shown that lavender aromatherapy may be effective when used with acupressure for short-term relief of lower back pain. further research is needed before firm conclusions can be drawn. | c |
| neoplasms | perillyl alcohol (poh), derived from lavender, might be beneficial in the treatment of some types of cancer. this research has focused on cancers of the pancreas, breast, and intestine. preliminary small studies in humans suggest safety and tolerability of poh, but effectiveness has not been established. | c |
| otalgia unspecified | a small clinical trial used a naturopathic eardrop called nhed (containing allium sativum, verbascum thapsus, calendula flores, hypericum perfoliatum, lavender, and vitamin e in olive oil) with and without an antibiotic and topical anesthetic. it was found that the ear pain was self-limiting and resolved after a few days with or without antibiotics. this evidence is preliminary and further research is needed before a conclusion about this treatment can be made. | c |
| other alopecia | small trials have shown that patients who massage essential oils (thyme, rosemary, lavender, and cedarwood) into their scalps daily showed more improvement than the control group. more research of lavender alone is needed before a strong recommendation can be made. | c |
| other specified postpartum complications | early evidence suggests a potential role for lavender aromatherapy, especially in combination with massage or acupressure, in the improvement of measures of quality of life among new mothers. more studies are needed. | c |
| pain | preliminary research suggests that the impression of pain intensity and unpleasantness may be reduced after treatment with lavender therapy. other research has shown that lavender aromatherapy may be effective when used with acupressure for short-term relief of lower back pain. further research is needed before firm conclusions can be drawn. | c |
