The plant is known for its distinctive yellow flowers that resemble dandelions and its broad, heart-shaped leaves. Coltsfoot has a long history of use in traditional herbal medicine, particularly for respiratory conditions.

Caution

While coltsfoot has been used traditionally for its medicinal properties, it should be used with caution. The leaves and flowers contain pyrrolizidine alkaloids, which can be toxic to the liver and potentially carcinogenic in high amounts or with long-term use. Because of this, it is generally advised to limit consumption and avoid prolonged use. Pregnant or breastfeeding women, as well as individuals with liver issues, should avoid using coltsfoot.

As with any herbal remedy, consulting a healthcare provider before using coltsfoot leaf is advisable, especially for those with existing health concerns or who are taking other medications.
