Question: Can Eucalyptus Leaves Be Harmful?

Eucalyptus leaves are great for coughs, colds, etc. But is it true that if they are not harvested at the right time, they are carcinogenic? If so, in what period should they be collected?

Eucalyptus: Answer: the active ingredients contained in eucalyptus leaves.

Dear Giuseppe,

eucalyptus is a large tree native to Australia, where it reaches majestic dimensions; in Italy it has been naturalized in some Ligurian and Lazio areas, where there are specimens up to thirty meters high.

It is a medicinal plant, used both in herbal medicine and in the production of drugs and perfumes; mainly the essential oil is used, extracted from the foliage, which contains some active ingredients, such as eucalyptol, canee, pinene, flavonoids. The properties of this tree are many, the active ingredients contained in the leaves are used for their balsamic, expectorant, antimicrobial powers; Recent research has emphasized that the ingestion of eucalyptus-based products, in conjunction with anti-inflammatory drugs, would improve and speed up their metabolism by our body.

The essential oil and mother tincture of eucalyptus are obtained from the oldest leaves, which are at least one year old, because they are richer in it. There is no scientific research indicating that the active substances contained in eucalyptus leaves are of a different nature depending on the period of the year in which the leaves themselves are picked.

It is clear that, as with any drug, and for many medicinal plants, the ingestion of large quantities of eucalyptus mother tincture, or essential oil, is strongly discouraged, because in large doses these substances are highly toxic.

Certainly another is the problem related to eucalyptus leaves: in some Italian regions these trees are grown to use their branches in the preparation of cut flowers.

For this reason the trees are always kept free from parasites and diseases, often practicing preventive treatments based on sulfur or copper. If you want to use the eucalyptus leaves dried by taking them in nature, be careful not to collect from trees that have been treated with chemicals by man.
