Other Information


Eupatorium cannabinum, also known as hemp-agrimony, is a species of perennial herb in the Asteraceae family. It is native to Europe, Asia and North Africa. The plant can grow up to 2 meters tall and has large clusters of small, pinkish-purple flower heads. The leaves are green and have a rough texture. Eupatorium cannabinum is commonly found in damp, marshy areas and along riverbanks. It is known for its medicinal properties and has been traditionally used to treat a wide range of ailments, including wounds, fever, and digestive issues. The plant also has a long history of use as a diuretic, and it is also sometimes used as a substitute for marijuana. However, it is not a source of THC, the primary psychoactive component of marijuana.


Hemp Agrimony, also known as Eupatorium cannabinum, is a plant native to Europe and Asia that has been used for medicinal purposes for centuries. It is a tall, herbaceous perennial that grows up to 6 feet tall and produces clusters of small pink or white flowers.

In traditional medicine, Hemp Agrimony has been used to treat a variety of ailments, including digestive problems, respiratory issues, and skin conditions. The plant contains a variety of compounds, including flavonoids, tannins, and essential oils, which may contribute to its therapeutic effects.

One of the most well-known uses of Hemp Agrimony is as a diuretic. It has been used to increase urine production and promote the excretion of excess fluids from the body. This makes it useful for treating conditions like edema, where there is a buildup of fluid in the body.

Hemp Agrimony has also been used to treat digestive problems, including diarrhea and dyspepsia. Its astringent properties may help to reduce inflammation and soothe the digestive tract.

In addition, Hemp Agrimony has been used topically to treat skin conditions like eczema and psoriasis. The plant's anti-inflammatory and antimicrobial properties may help to reduce inflammation and prevent infections.

Recent studies have also suggested that Hemp Agrimony may have anti-cancer properties. The plant contains compounds like flavonoids and terpenes, which have been shown to inhibit the growth and spread of cancer cells in laboratory studies.

While Hemp Agrimony has been used safely for centuries, it is important to note that it can cause side effects in some people. These may include gastrointestinal upset, headaches, and skin irritation. It is also important to talk to your healthcare provider before using any herbal remedy, especially if you are pregnant, breastfeeding, or taking medication.

Hemp Agrimony is also known for its anti-inflammatory properties, which may help to reduce pain and swelling in the body. This makes it useful for treating conditions like arthritis, where there is inflammation in the joints.

In addition, Hemp Agrimony may have immune-boosting properties. It contains compounds like polysaccharides, which have been shown to stimulate the immune system and improve overall health.

The plant may also have cardiovascular benefits. Its flavonoid content may help to improve blood flow and reduce the risk of heart disease.

Hemp Agrimony is typically consumed as a tea or tincture, although it can also be taken in capsule form. The plant is widely available at health food stores and online retailers.

It is important to note that while Hemp Agrimony has many potential health benefits, it should not be used as a substitute for conventional medical treatment. If you have a medical condition, it is important to talk to your healthcare provider before using any herbal remedy.

Hemp Agrimony is also an attractive plant that is commonly used in landscaping and gardening. Its tall, upright habit and clusters of pink or white flowers make it a popular choice for borders and naturalistic gardens.

The plant is also attractive to pollinators like bees and butterflies, making it a valuable addition to any garden or landscape that aims to support biodiversity.

Hemp Agrimony is a hardy plant that is relatively easy to grow. It prefers moist, well-drained soil and partial to full sun. The plant can tolerate a wide range of soil types and is relatively resistant to pests and diseases.

In addition to its medicinal and aesthetic uses, Hemp Agrimony has also been used for practical purposes. The plant's strong stems have been used to make baskets, mats, and other woven items, while its leaves have been used as a natural dye.

Hemp Agrimony has also been used in traditional folk medicine to support the respiratory system. The plant's expectorant properties make it useful for treating coughs, bronchitis, and other respiratory conditions. It may also help to relieve congestion and promote easier breathing.

Additionally, Hemp Agrimony has been used as a natural insect repellent. The plant contains compounds that repel insects like mosquitoes and ticks, making it a useful addition to gardens and outdoor spaces.

Hemp Agrimony is also sometimes used as a natural remedy for anxiety and stress. The plant's calming properties may help to reduce anxiety and promote relaxation.

Finally, it is important to note that the use of Hemp Agrimony is not without controversy. The plant contains compounds that are structurally similar to THC, the psychoactive compound found in marijuana. While Hemp Agrimony is not psychoactive and does not produce a "high" like marijuana, some countries have regulated its use due to concerns about its potential to be misused as a recreational drug.

In conclusion, Hemp Agrimony is a versatile plant with a wide range of potential uses. From its medicinal properties to its aesthetic appeal and practical applications, Hemp Agrimony is a valuable addition to any garden or landscape. While more research is needed to fully understand its therapeutic potential, Hemp Agrimony is a promising plant with a long history of use in traditional medicine. As always, it is important to use caution and consult with a healthcare provider before using any herbal remedy.
