What Is Cow Parsnip?
Cow parsnip (Heracleum maximum) is a flowering plant native to North America.
It is a tall herbaceous perennial, growing up to 10 feet tall, with large leaves and umbrella-shaped clusters of small white flowers.
It can be confused with giant hogweed but is smaller in size and lacks purplish spots and sharply serrated leaves.
Cow parsnip is found throughout North America and is commonly used as pasture plant for livestock and a food source for wild animals.
However, it contains furanocoumarins, which can cause skin blisters and hyperpigmentation when exposed to sunlight.
Despite this, cow parsnip has various traditional uses, such as a dermatological aid, swelling treatment, drinking straws, flute making, and bug repellent.
It is also possible to create a yellow dye from its roots.

Did You Know?
1. Cow parsnip, scientifically known as Heracleum maximum, belongs to the carrot family and is an herbaceous perennial plant.
2. Despite its name, cow parsnip is not actually related to the true parsnip (Pastinaca sativa). It is more closely related to other plants like celery and carrots.
3. The sap of the cow parsnip plant contains a chemical compound called furanocoumarins, which can cause a severe skin reaction known as phytophotodermatitis when exposed to sunlight.
4. Native American tribes, such as the Cheyenne and Blackfoot, used various parts of the cow parsnip plant for medicinal purposes, including treating respiratory problems and gastrointestinal disorders.
5. Cow parsnip plants can grow quite tall, reaching heights of up to 10 feet (3 meters) in some cases. Their large umbrella-shaped clusters of white flowers can span almost a foot (30 centimeters) in diameter.

Potential Health Risks
While cow parsnip provides notable benefits, it is important to note the potential health risks associated with this plant. Cow parsnip, much like its close relative giant hogweed, contains furanocoumarins in its sap. These chemicals have phototoxic properties, meaning they react with ultraviolet light and can cause skin blisters and hyperpigmentation when in contact with the skin and exposed to sunlight. If you come into contact with cow parsnip sap, it is crucial to cleanse the affected area immediately and protect it from sunlight to prevent further irritation and discomfort. It is always wise to exercise caution when handling this plant.
- Cow parsnip contains furanocoumarins in its sap, similar to giant hogweed.
- Furanocoumarins in cow parsnip sap have phototoxic properties.
- Contact with cow parsnip sap can cause skin blisters and hyperpigmentation.
- Cleanse the affected area immediately if in contact with cow parsnip sap.
- Protect the affected area from sunlight to prevent further irritation.
- Exercise caution when handling this plant.
Comparison With Giant Hogweed
Cow parsnip is often confused with Heracleum mantegazzianum, commonly known as giant hogweed. However, there are several key distinctions between the two plants. Cow parsnip is smaller in size compared to giant hogweed and lacks the characteristic purplish spots and sharply serrated leaves of its larger counterpart.
It is also similar in appearance to other invasive Heracleum species and certain species of the genus Angelica. While giant hogweed poses a greater risk to human health due to its higher concentration of furanocoumarins, it is still important to exercise caution around cow parsnip to avoid any potential irritation caused by its sap.
