Even though peppermint is not poisonous, too frequent consumption can cause discomfort. Especially people who are prone to heartburn should use peppermint sparingly.
Peppermint does not contain toxins
You can safely harvest and enjoy peppermint even after it has flowered. Unlike other herbs, the leaves do not accumulate excessive levels of essential oils.
The herb is popularly used as a tea or oil for ailments such as:
- Stomach and intestinal cramps
- Sleep problems
However, peppermint can aggravate discomfort caused by heartburn. The essential oils have an irritating effect on the stomach walls, so even healthy people can experience problems after taking too much peppermint. This is especially true for peppermint oil, which should never be taken undiluted.
