Twenty-eight patients with xerostomia participated in a blind, placebo-controlled
longitudinal study of the possible effects of homeopathic medicines on oral discomfort.
All patients were first divided in two groups according to their medication. After
that the two groups were randomly assigned according to a coin-toss to the experimental
or control group. Most patients had systemic diseases, such as rheumatoid arthritis
and/or Sjögren's syndrome, and frequent daily medications. The randomly selected experimental
group (n=15) got an individually prescribed homeopathic medicine and the control group (n=13) a placebo substance (sugar granules), both for 6 weeks. Neither group knew of
the nature of the medicine. Oral dryness was evaluated by measurement of unstimulated
and wax-stimulated salivary flow rates and visual analogue scale. With only two exceptions,
the experimental group experienced a significant relief of xerostomia whereas no such
effect was found in the placebo group. Stimulated salivary flow rate was slightly
higher with homeopathy than placebo but no consistent changes occurred in salivary
immunoglobulin (IgA, IgG) levels.
In an open follow-up period those receiving homeopathic medicine continued treatment
and the placebo group patients were treated with individually prescribed homeopathic
medicines. The symptoms of xerostomia improved in both groups.
Our results suggest that individually prescribed homeopathic medicine could be a valuable
adjunct to the treatment of oral discomfort and xerostomic symptoms.
