Aromatherapy is particularly effective for stress, anxiety, and psychosomatic induced problems, muscular and rheumatic pains, digestive disorders and women's problems, such as PMS, menopausal complaints and postnatal depression. Here is a summary of the results from clinical studies:

Behavior

Considerable evidence exists that fragrant compounds have a profound effect on our mind and behavior. Animal studies have found that hyperexcited mice (as a result of consuming a large quantity of caffeine) was calmed by the aroma of lavender, sandalwood, and other oils sprayed into their cages. The same mice were found to become very irritable when exposed to the aroma of orange terpines, thymol, and some other substances. These oils were all detected in their bloodstream after about an hour.

Sleep

In a study reported in the British Medical Journal Lancet, elderly patients slept "like babies" when a lavender aroma was wafted into their bedrooms at night. These patients had complained of difficulty falling asleep and had to take sleeping pills to get sleep prior to the aromatherapy.
Postpartum discomfort

In a double blind study, 635 women applied lavender oil to their perineal area (part of the body between the vagina and the rectum) after child birth. The women reported a distinct improvement between the third and fifth day. (The discomfort is the worst during this time for patients in the control group.)

Colds

It has been well established that chicken soup is good for cold (both historically and scientifically). Studies were conducted to find out whether the effect was due to the action of the hot steam on the lining of the nostrils or whether the aroma of the chicken soup has anything to do with it. The results indicated that chicken soup was more effective than the steam indicating the effectiveness of the aroma.

Stress

In a study conducted at the Memorial Sloan-Kettering Hospital in New York, patients undergoing magnetic resonance imaging (MRI) reported 63 percent less claustrophobic after getting exposed to the aroma of vanilla. There was no change in their heart rate. Obviously, the aroma reduced their anxiety probably by the pleasant memories evoked by the vanilla aroma or by some other physiological response.

In another study, 122 patients who were in an intensive care unit, reported feeling much better when aromatherapy was administered with the oil of lavender (compared to when they were simply given a massage or allowed to rest.) No changes in the patients who were given aromatherapy was observed in the blood pressure, respiration, or heart rate. As we mentioned before, Japanese have reported less mistakes by keypunch operators when exposed to fragrance.

Male Sexual Response

Circulation to the male sexual organ was found to have improved substantially by treatment with licorice or lavender with pumpkin pie. Doughnut with black licorice was also very effective. Men who are considered the most sexually active responded well to lavender, cola, and oriental spice; older males preferred the fragrance of vanilla. These studies prove that aromatherapy is an effective therapy for the treatment of male impotence from the blood vessel disease or from psychogenic factors.
