Dr Balfour discusses some of the issues and problems which often arise when treating asthma homoeopathically. One of the obstacles often faced is the reappearance of old skin symptoms such as eczema which in turn should be treated homoeopathically. He stresses the importance of waiting for the remedy to take action and ignoring any aggravation which might arise. He mentions some of the remedies which have been effective in his experience including Lycopodium clavatum and more unusual remedies such as Ambrosia and Oleander, and discusses the use of inhalers. He finally shares a case cured by Phosphorus and Phosphoric acid.

A case is related of an eleven year old boy who suffers severe asthmatic attacks usually during the night. Following detailed case analysis an M potency of Natrum sulphuricum is prescribed on the basis of seven key symptoms. This is effective for a while then the attacks resume. Arsenicum album, which was also indicated in some of the symptoms, is then administered in a Q potency. He does well on this for around four months apart from a skin eruption and a diarrhoea attack but no remedy is administered for these. The boy then comes down with a cough, coryza and sneezing and Natrum sulphuricum M is administered with success and is repeated at long intervals and increasing potency.

Dr Blackie has treated at least sixty cases of asthma with varying success over the years and here she discusses a series of cases divided into children, adults with a family history and adults without a family history. Among the children's cases is a seven year old girl with a history of bronchitis since infancy and asthma since the age of five. She was initially proscribed Tuberculinum bovinum 200 on which she improved for four months but subsequently her condition worsened and repeat prescriptions of the remedy were not effective, however Spongia tosta 6 was administered in 6 doses at two-hourly intervals and helped to keep wheezing at night in check. Over the next two years, Arsenicum album, Carbo vegetabilis, Sambucus, Ipecacuanha, and Antimonium tartaricum were prescribed with varying success but the patient had still not overcome her asthma to a degree which would be regarded as successful. Then, after a particularly bad attack, Natrum sulphuricum 10M was prescribed on the basis of the symptoms of breathlessness, holding on to her chest at intervals and sensation of a lack of air in the chest, and this prescription was very effective, giving almost complete relief for two winters. Dr Blackie discusses a further three cases of children who were treated with Tuberculinum bovinum, Psorinum, Thuja occidentalis, Pulsatilla, Sambucus and Phosphoric acid. She goes on to discuss adults with a family history of asthma for whom Kalium sulphuratum and Carbo vegetabilis were effective, and adults without any family history or any allergic condition for whom Phosphorus and Cactus grandiflorus worked well.

In this series of articles Dr Blunt discusses his successes in the treatment of asthma with the remedy Natrum muriaticum. He states that in the repertories this remedy has not been accorded the recognition it deserves in its ability to treat asthma, and it is not mentioned under several symptoms which he has had success in curing with this remedy. Natrum muriaticum has been a specific for more than half the cases of asthma which he has treated and is the remedy which he immediately thinks of when presented with a new case unless further investigation rules it out. He discusses the case of a woman whose symptoms - asthma worse in wet weather, attacks worse between 2 and 3 a.m., able only to sleep upright and with a pustular eruption on both sides of her hands - did not point to Natrum muriaticum but which nevertheless were cured by it. As a result Dr Blunt has drawn up a list of six key symptoms which should point to Natrum muriaticum. In the third article Dr Blunt puts forward that salt aggravates psora in our bodies and thus is reponsible for many asthma cases - for this reason Natrum muriaticum can be used homoeopathically to treat asthma.
