Despite the many benefits of nettle tea, it should be used with caution due to its potential harms. Just as the nettle herb has high nutritional value, it also has some aspects that may cause harm, especially when consumed excessively, and thus can pose a danger to health. In this article, we will review the most prominent harms of nettle tea and how it can be consumed correctly to avoid its potential harms.
What is the nettle plant?
The nettle plant is a perennial herbaceous plant famous since ancient times for its powerful properties and its direct effect when it comes into contact with the skin. Its stems and leaves are covered with tiny hairs that act as microscopic needles, releasing natural irritating substances that cause itching, burning, and skin redness. This plant belongs to the nettle family and grows in humid and temperate environments, which has made it widespread in various parts of the world. Despite its stinging nature in its raw form, it acquires great nutritional and medicinal value when dried, boiled, or properly processed. Its leaves turn into a rich source of nutrients and beneficial plant compounds.
It has been used since ancient times in traditional medicine to support general health, reduce joint inflammation and urinary tract disorders, compensate for mineral deficiencies, and support the body with antioxidants. However, despite this, there are harms of nettle tea that can appear when consumed incorrectly or excessively.
Harms of nettle tea
Despite the many benefits of nettle tea, it is not without some harms, so let's discover them together:

Oral consumption of the nettle herb may lead to some digestive disorders in a group of users, such as diarrhea or constipation, stomach pain, and nausea. Some individuals may experience some intestinal cramps, especially when consumed in inappropriate doses or for long periods.
Harms to the skin:
When the nettle herb, especially fresh leaves, touches the skin, it may cause skin irritation, such as itching, redness, a tingling sensation, or burning. An allergic rash may appear in individuals with sensitive skin, so it should not be used topically without prior processing.

In some rare cases, this herb may lead to severe allergic reactions such as persistent rash, difficulty breathing, swelling of the face, lips, tongue, or throat. These are among the most dangerous harms of nettle tea, so immediate cessation of use and seeking medical help is necessary.
