In 1992, the "Riza Psicosomatica" magazine published an article which reported the results of a number of tests carried out by a group of doctors on the use of the OTOSAN ear cone. From this research it emerged that the cone may be efficacious in certain pathological conditions of the ear and principally on two very frequent complaints: the obstruction of the ear duct due to wax and otalgia during otitis.

In the first case 15 adults were tested. They presented an abundance of earwax, or the actual formation of a plug, and complained of itchiness, difficulty in perceiving sounds, buzzing and hissing sounds. After the cone had been applied, all patients reported an immediate improvement of their symptoms and when examined using an otoscope a decrease in wax could be observed.

In the second case 15 schoolchildren suffering from otalgia who had not taken pain-killers for at least six hours were considered. Most of the children reported a remarkable reduction in pain after only five minutes from the end of the treatment with the cone. At a test carried out two hours later the pain had not returned. As a result of these tests, doctors have formed a positive judgement on the use of the OTOSAN cone.

The OTOSAN cone indirectly acts on the points used in acupuncture revitalising them and creating a beneficial relaxing effect in the user.

In Germany, in 1995, a television programme entitled "An hour in the doctor's surgery" was broadcast containing some interviews on the use of ear cones. Among the interviewees Mrs Ulrike Lorbiezki said: "I use ear cones on my children as a supplementary remedy against heavy colds and flu. Especially Tassilo who is five and has a particular tendency for colds followed by inflammation of the lateral cavities and of the ears. I always use the cones on both ears when the cold persists and begins to settle into the nose. I carry out the treatment before putting them to bed, because I have noticed that the children sleep more peacefully during the night. In this way I cure the cold using fewer drugs". In the course of the same programme Klaus Krieg, a homeopath, stated that he applies the cones also to patients suffering from headaches, migraine, sinusitis, neuralgia and pains resulting from stress. Mr Jungfer, one of Krieg's patients, said: "About three years ago I used to hear buzzing in my ears. I always had a strange sensation and woke up during the night. I went to the doctor, had x-rays done, but I wasn't satisfied with the results because symptoms persisted. Ever since Dr. Krieg treated me with ear cones problems have disappeared. The therapy is effective and still today I undergo treatment every four weeks".

The University of Pavia, following various clinical and dermatological tests in its laboratories, released a positive testimonial on the use of the OTOSAN cone.

Therefore, thanks to continuous research into the quality and safety of the product, the OTOSAN cone has obtained the qualification of class one medical device.

The "Remedies from Nature" Encyclopedia, edited by the Reader's Digest, mentions the oldest method for the removal of earwax: the use of cones made from waxed cloth.
