List of dangerous medicinal plants for children

Dangerous home remedies for children

I would be impossible to list all the potentially toxic medicinal plants for children. Below are listed only the home remedies that have been proven very harmful to children and those that attract the most hospital poisoning.

Dangerous essential oils for children

The majority of poisonings by plants in children are produced by the use of remedies or preparations with essential oils. Many cases of intoxication have been described, which can be more or less serious, depending on the type of plant, the concentration that has been used, and the sensitivity of the child to that plant.

Poisonings by essential oils can give problems as serious as ulcers, tachycardia or liver failure. For this reason these remedies are totally contraindicated in babies and children, both in internal use and external use.

  • The use of essential oils in children is the main cause of poisoning by medicinal plants in children.
  • Essential oils should not be used on children and should always be kept out of sight and reach.

The administration of plants with salicylates in children from 0 to 12 years old can develop Reye’s syndrome, a disease with serious results in the liver and brain, which is attributed to the use of aspirin when they have the flu or chickenpox. For the same reason, children should not be given aspirin either.

Other poisonous plants that produce poisonings

In the previous table, cases of poisoning by poisonous plants have been excluded, which are not the reason for this article. However, some of the aforementioned, such as nutmeg, comfrey, lemongrass or castor bean, are clearly not recommended plants, neither in adults, nor in children, due to their potentially dangerous effects.

There are many poisonings in children from the ingestion of indoor plants – most of which are toxic, such as diefembaquia (Diffenbachia spp.); or by ingesting very toxic garden plants, such as oleander (Nerium oleander) or lily of the valley (Convallaria majalis), toxic forest plants, such as rhododendron (Rhododendron ferrugineum) or aconite (Aconitum napellus), or berries and red fruits of the forest that are poisonous like carmine grass (Phytolacca americana).
