Boneset is the common name given to several perennials of the Eupatorium genus. This genus is a part of the Aster family (Asterium), and is known for its many medicinal properties as well as its attractive appearance. The versatile properties of the plant have given rise to names such as agueweed, feverwort, and the sweating plant amongst many more!

Native to the United States and Canada, these flowers have been called ‘boneset’ for ages because of their use in setting fractured bones to promote healing. They were also used to treat dengue or ‘breakbone’ fever. The flower was apparently discovered by Native Americans and used in medication for centuries before we discovered it. When the colonists arrived, they were taught the various uses of the plant and the flower too.

Here is a detailed account of the ecology of the plant, its uses in various illnesses and diseases, and all the different species that come under the boneset umbrella.

The plant can reach a height of 5 feet with its erect, rotund, and hairy stem that branches only on top. The leaves are large and arranged directly opposite each other; they are largest at the bottom and continue to progressively become smaller as they reach the top of the branch.

The flowers bloom between July and September in white or purple clusters at the ends of branches. Each bunch consists of 10-20 florets. The different species that are called boneset often have much different inflorescence and appearance in general.

The common boneset plant needs a damp environment, and hence, it is readily found in marshes and meadows near wooded areas. It is most often found in eastern US and Canada, ranging from Nova Scotia to Florida.

It is often planted by farmers for its substantial pollinating properties. The flowers attract sweat bees, small carpenter bees, digger and bumble bees. However, it is also highly attractive to pests.

Except the roots, all parts of the plant have medicinal value. The plant is harvested after the flowering has begun. After harvesting, the components of the plant can be extracted and separated in water or alcohol. It can also be used as a fresh or dry herb.

It is usually taken as a tea steeped in a cup of boiling water for 10-15 minutes. The taste of the tea is bitter, so honey and lemon are added to the infusion to make it more flavorful.

Medicinal Uses

Medicinal uses of boneset flower

The Native Americans called the plant ‘agueweed,’ where ague is the name for malarial fever. They used it for other infectious diseases as well, such as influenza and colds. Fever, arthritis, asthma, rheumatism- no disease is a match for the boneset plant.

By the 18th century, European settlers had started considering the plant to be an all-encompassing treatment for common ailments. Dried boneset was a staple in every household and even doctors kept it on hand for immediate use during flu season!

Other uses include the treatment for headaches, skin conditions, jaundice, nasal inflammation- and even secondary symptoms that arise from such diseases- bronchitis, pneumonia, and tonsillitis.

Types of Boneset Flowers

There are several species of the Eupatorium genus that are referred to as boneset. Have a look at the most interesting ones:

Common Boneset

Eupatorium perfoliatum

When people talk about the common boneset, they mean the Eupatorium perfoliatum. The plant grows to be about a 100 cm tall, with leaves that hug the stems. The flowers are in dense clusters of florets held slightly above the foliage and have a pleasant floral scent. This species is able to form hybrids with others from the same genre.

The plant prefers being in full or partial shade in moist conditions. The soil must have organic material so it can retain water and help the plant bloom. Pests and diseases cannot usually do much to harm the foliage.

This is the most commonly and naturally found perennial out of all the members of the genus. Its medicinal uses are widely recognized.

The stem of the plant is about a 100 cm tall with short rhizomes. The flowers are tiny, white florets arranged in flower heads. It is pollinated by insects alone since it is self-incompatible. Only a dozen naturally occurring populations have been found which is why the plant is one of the rarer species of the genus.
