What Is Loco Weed? Unveiling the Curious Effects of This Intriguing Botanical
What Is Loco Weed?
Loco weed, also known as Locoism, refers to the poisonous effects caused by consuming certain plants from the Fabaceae family.
This condition predominantly affects livestock, including cattle, sheep, horses, elk, and deer.
Loco weed contains the alkaloid swainsonine, which interferes with the metabolism of alpha-mannosidase, leading to neurologic signs and severe health issues in affected animals.
Loco weed can be found in North America, particularly in plants of the Oxytropis and Astragalus genera, as well as in Swainsona plants in Australia.
The economic impact of loco weed on livestock production has been a concern since its discovery in the late 19th century.
Remedies for locoism include avoiding pasture contaminated with loco weed, providing supplemental nutrients, and using conditioned food aversion techniques with lithium chloride.

Did You Know?
1. Loco Weed, also known as Datura stramonium, is a highly poisonous plant native to North America. Ingesting even small amounts can cause hallucinations, delirium, and in some cases, death.
2. While Loco Weed is extremely dangerous, it has been used medicinally in some Native American cultures. Small doses of its active compounds have been employed to treat asthma, skin conditions, and even dental pain.
3. This notorious plant got its nickname “Loco Weed” due to the bizarre behavior it induces in animals if they eat it. Horses, in particular, exhibit unusual and erratic movements, leading to the Spanish name “loco” meaning “crazy.”
4. Loco Weed’s petals have an intriguing property: they can change color based on environmental conditions. Depending on the soil pH, Datura stramonium’s flowers can transition from white to purple or even pink hues.
5. The seeds of Loco Weed have been used for divination purposes by some Indigenous tribes. It was believed that by observing the movement of these seeds, one could predict the future or obtain insights into a person’s fate.
What Is Loco Weed – Loco Weed
Loco weed, also known as locoweed or crazyweed, is a group of plants that contain a powerful neurotoxic chemical called swainsonine. Swainsonine is an alkaloid found in various plants belonging to the Fabaceae family, including species like Oxytropis in North America and Swainsona in Australia. These plants have been recognized for their peculiar effects on livestock, causing a condition known as locoism. Locoism impacts various animals such as cattle, sheep, horses, elk, and deer.
Swainsonine
Swainsonine is a potent alkaloid that acts as a competitive inhibitor of the alpha-mannosidase enzyme.
- The alpha-mannosidase enzyme is responsible for breaking down complex carbohydrates in the body.
- When swainsonine inhibits the activity of alpha-mannosidase, it accumulates mannose-containing compounds in various tissues.
- This accumulation of compounds causes neurologic signs in affected animals.

Livestock
The effects of loco weed toxicity can vary among different species of livestock. Cattle, for example, may show signs of depression, ataxia, tremors, and weight loss. Sheep, on the other hand, may display weakness, staggering, and incoordination. Horses affected by loco weed may exhibit neurological symptoms such as incoordination, disorientation, and muscle tremors. Elk and deer are also susceptible to locoism, experiencing similar neurological manifestations.
Swainsona In Australia
In Australia, the plant Swainsona, commonly known as Sturt’s desert pea, has been associated with swainsonine poisoning in livestock. The plant is native to the continent and has caused both economic and health concerns within the agricultural industry. Swainsona poisoning in Australia has been primarily observed in sheep grazing on Astragalus pehuenches, which contains swainsonine.
Economic Impact And Remedies
The economic impact of loco weed on livestock production has been significant. The ingestion of loco weed-infested pasture by animals leads to reduced weight gain, decreased milk production in cows, and reproductive problems.
Remedies for loco weed poisoning include:
- Removing affected animals from the contaminated pasture
- Providing supplemental nutrients to aid in recovery
Additionally, conditioned food aversion using substances such as lithium chloride has been employed to discourage animals from consuming loco weed.
loco weed is a group of plants containing the neurotoxic chemical swainsonine, which can cause locoism in various species of livestock. Swainsonine inhibits the enzyme alpha-mannosidase, leading to the accumulation of mannose-containing compounds and resulting in neurological signs. The occurrence of locoism has been reported in different regions worldwide, including North America, Australia, and South America. Its economic impact on the livestock industry has emphasized the need for effective remedies and management strategies to mitigate the adverse effects of loco weed on animal health and productivity.

Frequently Asked Questions
What does loco weed do?
Loco weed, often referred to as crazyweed, can have detrimental effects on animals who consume toxic amounts of it. Usually, symptoms start emerging within six to eight weeks after grazing on the weed, although the specific amount needed to be ingested varies depending on the plant and animal species involved. These symptoms typically entail listlessness and depression, accompanied by lowered head, weakness, and loss of coordination. As the condition progresses, the animal may experience paralysis, rendering them unable to eat or drink, ultimately leading to their demise.
How do you get rid of loco weed?
To effectively eliminate loco weed, the prevailing method entails utilizing a popular commercial product combining one part picloram with four parts 2,4-D. This blend has proven to be widely successful in curbing the growth and presence of loco weed. By applying this mixture diligently and according to the recommended guidelines, one can effectively eliminate the persistent threat of loco weed in commercial settings, ensuring healthier vegetation and a more vibrant ecosystem.
When addressing loco weed, the commonly employed solution involves the usage of a commercial herbicide blend. A combination of one part picloram with four parts 2,4-D has emerged as the go-to choice for controlling and eradicating loco weed successfully. By following the prescribed instructions and applying this mixture consistently, the detrimental effects of loco weed can be mitigated, clearing the way for more desirable flora to thrive and enhancing the overall ecological balance in the affected areas.
What is the origin of the word locoweed?
The word locoweed originates from a loanword from Spanish, where “loco” means crazy. It was first documented among English speakers by 1844 and is commonly understood to refer to a plant with intoxicating or mind-altering properties. The term locoweed bears a connection to the Spanish word, highlighting its association with a state of madness or eccentric behavior.
What is local weed?
Local weed refers to a specific variety of wild plants that grow in a particular region. These plants can include various species, but one example is locoweed, a perennial plant from the bean family. Locoweeds are characterized by their hairy texture and vibrant racemes of flowers in shades of white, pink, yellow, or purple. While they may add visual appeal to the local landscape, they pose a significant threat to grazing animals as they contain toxins harmful to their health. Therefore, locals must be cautious about the presence of these toxic plants to ensure the well-being of their livestock.
