Allergies: when indoor plants make you sick

Indoor plants are decorative and ensure a good indoor climate.

Indoor plants offer many health benefits: they produce oxygen and humidify the air in the room. Some species can even filter toxins from the air. However, certain houseplants cause allergic reactions such as runny nose, itchy eyes, coughs or rashes in some people. The triggers for this can be leaves, pollen or the sap of the plants. Even without touch, some people sometimes react violently. If an allergy is suspected, a doctor should be consulted.

Ficus and rubber tree can cause allergic reactions

Some people are allergic to popular houseplants such as the ficus.

Popular indoor plants such as weeping fig (Ficus benjamina) and rubber trees are among the more common causes of allergic reactions. The triggering substances, the allergens, are in the sap and reach the leaf surface. There they combine with dust and get into the room air. The allergen of the ficus is similar to the latex allergen. Anyone who has such an allergy should therefore better avoid indoor plants such as rubber trees, Christ thorns and poinsettias.

Allergies to flowering plants and cut flowers

Some people also have an allergic reaction to cut flowers, especially flowers from the daisy family. These include, for example, asters, daisies and sunflowers. Early bloomers such as hyacinths, tulips, and Inca lilies can also cause reactions. This also applies to primroses. Newer breeds with the designation "Touch me" should not cause irritation.

Avoid mold in potting soil

If you want to avoid moldy potting soil, you can rely on hydroponics with expanded clay balls.

Excessive watering can cause mold to form in potting soil, the spores of which can also trigger allergic reactions. Usually the infestation shows up as a white layer on the ground. However, the infestation can also be in the root area and thus not be visible. Even if there is no allergy, the moldy soil should be disposed of immediately. Instead of potting soil, you can create a hydroponic culture, the plants then do not root in soil, but in a substrate such as expanded clay or clay granulate.

Indoor plants can relieve pressure on the airways

Plants can also have advantages for allergy sufferers - especially those that have a relatively high water consumption. Due to high evaporation, they increase the humidity in the room, which can relieve the airways and mucous membranes. It is important to choose house plants with large leaves so that the oxygen exchange is as large as possible. These plants release more than 90 percent of the moisture absorbed by the irrigation water back into the room air. Important: The leaves should be cleaned of dust regularly.
