Inhalation therapy with home remedies: Myths and effective methods – lung specialist Prof. Rainald Fischer explains

Lavender oil, eucalyptus oil, homemade saline solution and other substances are often applauded as effective home remedies for inhalation therapy. According to Prof. Rainald Fischer, they deserve no such praise. In an interview, he discusses effective methods and the risks of inhalation therapy with home remedies.

PARI blog: Inhalation therapy with so-called home remedies is extremely popular. One method is inhaling salt through hot steam. What do you as a pneumologist think of this?

Prof Dr Fischer: I am not at all impressed by the idea of this home remedy for inhalation therapy for the lungs. First of all, the salt crystals stay in the water. This is because salt has a higher boiling point than water. So the salt stays behind in the bowl, pot or plastic inhaler and you only inhale hot steam, but no salt.

And secondly, the droplets are too large to reach the lungs. They stay behind in the mouth and throat, but do not reach the bronchial tubes and so cannot moisturise them and release the mucus coating them.

I am surprised time and again by how many people come to my consultancy telling me they have tried out salt inhalation with steam. I can only stress that this is ineffective for the lungs, so is no more than a quack method if you are trying to treat the bronchial tubes.

Saline solution only reaches the lower airways if it is inhaled through an electric inhalation device, also known as a nebuliser. If you have to or want to inhale with saline, please use a nebuliser. Everything else is a waste of time.

Added to this, unlike a homemade saline solution, with professionally produced and sterile-filled saline solutions you can be sure that the solution is not contaminated with unwanted substances. That is relevant. At the end of the day, you are breathing the saline solution deep into your bronchial tubes.

So please, firstly use a nebuliser for the inhalation therapy and secondly buy a specially produced saline solution from the pharmacy or a specialist supplier and do not inhale saline solution you have mixed yourself.

PARI blog: Another frequently cited home remedy against colds and coughs is inhalation therapy with essential oils such as eucalyptus oil or lavender oil and ointments for colds. What are your thoughts on this?

Prof Dr Fischer: Let’s put it this way: As a lung specialist, I cannot imagine this could be healthy in any shape or form. I do not want to have an oily substance in my lungs. That all has to come back out of the bronchial tubes.

Some people push the idea of inhalation therapy with essential oils with nebulisers. There are not enough studies on inhalation therapy with essential oils to properly estimate the efficacy and safety of this inhalation method. This is why this home remedy should be used with great caution.

This also applies given the background that the quality of the essential oils available on the market varies greatly. There are no strict rules for essential oils and so the labels on the products can have incomplete information on which substances are actually in the bottle. Sometimes the oils are mixed with cheaper substances, which has a negative impact on the quality.

There are several groups I would definitely advise to avoid inhalation therapy with essential oils or balsams for colds:

  • • Children under 6 years old. If taken in their purest form, essential oils can damage the central nervous system, the kidneys and the airways of children. In children under the age of two years, there is even the risk of a laryngospasm where the vocal cords suddenly spasm if they simply breathe in ointments for colds. Inhalation would be devastating.
  • Asthmatics of any age
  • People with a sensitive bronchial system
  • People with obstructive lung diseases such as COPD or cystic fibrosis

In these people, inhalation of essential oils can irritate the bronchial tubes and cause a tight chest with a cough and shortness of breath.

PARI blog: What other ideas do your patients come up with in terms of inhalation therapy with home remedies in your consultation?

Prof Dr Fischer: Several! And I usually advise them against home remedies. For instance, there is the idea of inhaling frankincense. Generally speaking, smoke will always irritate the lungs, so it is not an adequate remedy for this reason alone.

There are also patients who want to be prescribed cannabis and who want to inhale it in combination with tobacco – because it apparently expands the airways. If I have problems with tight bronchial tubes, I should of course treat this symptom by inhaling medications that expand the airways and not with tobacco that is proven to harm the tissue of the lungs.

According to pneumologists in the Association of Pneumological Clinics, studies also indicate that cannabis could cause patients to develop pulmonary emphysema and an accumulation of secretions in the lungs. Over time, this can lead to recurrent inflammation with structural damage to the airways caused by the development of bronchiectasis.

I sometimes don’t understand why people trust home remedies which are based on myths and word-of-mouth propaganda - more than they trust methods and medications that are clinically tested and safe and that are proven to be effective. Not everything with “homemade” and “natural” on the label is automatically healthy.
