Several plants, including poison hemlock, can kill humans and livestock. These plants also cause birth defects and other negative effects.

Western water hemlock, also known as the beaver poison, is native to North America. It grows in moist areas, including marshes and creeks.

Its leaves are arranged in a feather-like manner. Each leaf is oblong and lance-shaped. The leaflet veins run from the midrib to notches along the leaf edges. The leaflets are sharply pointed and toothed.

Western water hemlock is native to the Pacific Northwest. It is a perennial plant, which means that it grows year after year. It grows to between two and eight feet tall.

Its flower clusters are umbrella-shaped with four to six brown bracts. Each flower has two seeds.

Western water hemlock is extremely poisonous. The toxin in the plant causes nausea, vomiting, and convulsions. In addition, Western water hemlock can cause a range of other problems, including loss of livestock, damage to pastures, and other environmental effects.

When it comes to western water hemlock, some people choose to burn the plant. If you choose to burn the plant, be sure to wear appropriate protective clothing and equipment. It is also important to avoid contact dermatitis, which can result from burning hemlock.

Western water hemlock is also known as cowbane, water parsley, and beaver poison. It is one of the most toxic plants in North America. Its roots can kill 1,200-pound cows.

Water hemlock can be a serious problem for livestock, but good hemlock management can keep your livestock safe. It is especially important to keep livestock away from areas where the plant grows, such as wet areas and standing water.

If you think that your livestock may be infested with water hemlock, you should consult a weed control professional. These professionals can offer specific herbicide recommendations for your situation. Some herbicides, such as glyphosate, may be effective on small rosettes of plants, but may not be effective on mature plants.

Poison hemlock is a highly toxic plant that is widespread throughout North America. It is found in a variety of habitats, including forests, fields, pastures, and creeks. Its leaves and stems have a musty odor that resembles alkaloids.


Known for its poisonous leaves, water hemlock is one of the nastiest plants on Earth. Ingestion of the plant’s leaves and stems can cause severe, albeit temporary, side effects. Symptoms include dilation of the pupils, excessive salivation, bloat, and convulsions.

The scientific name for this is cicutoxin, an alkyne with a relatively long half-life in humans. In some studies, it has been shown to inhibit proliferation of lymphocytes. However, it is not easily excreted from the human body. In some cases, pregnant animals give birth to deformed offspring.

Cicuta is a relatively large plant, up to six feet in height. It grows in moist soils along ditches and streams. It has two species in North America, Cicuta douglasii and Cicuta maculata. Both species have fern-like leaves and umbels of tiny white flowers. Water birds like to eat the corky, rounded fruits of the water hemlock.

The plant is the subject of several studies. However, no one has yet pinned down the true mechanism of action. Some have suggested that the toxin is responsible for the plant’s toxic effects. Others claim that simply ingesting the plant’s leaves can result in death. In one case, a patient was hospitalized for two days after eating the root of Cicuta.

The name of the cicutoxin may sound like a mouthful, but it’s a pretty good guess as to what this chemical is. Its properties include its ability to block the GABA induced chloride current. However, the most impressive effect is its inhibition of a heptadienyl carbenium ion, which is a surprisingly common compound in nature.

The toxin has also been known to frighten humans. In one case, a patient was left with a fuzzy feeling in his head for two days after ingesting the root of Cicuta. In another case, the plant’s poison was actually the culprit behind a mild case of cardiac arrest. This is despite the fact that the patient was only a year old. The plant’s effects are also heightened by migration, when humans ingest the plant while on the move. The plant also happens to be an excellent source of vitamins C and E.

Symptoms of poisoning

Symptoms of poisoning from water hemlock include respiratory paralysis and muscle twitching. The symptoms usually appear within a few hours. A severe reaction can lead to respiratory failure, cardiac arrest, and death.

Symptoms of poisoning from water hemmock are not the same as those of poison ivy, sumac, or oak. The toxic alkaloids of the water hemlock plant produce a number of clinical signs including nausea, vomiting, dilated pupils, respiratory paralysis, and muscle paralysis. These signs can be life threatening, and must be treated immediately.

The water hemlock plant is toxic to both humans and animals. However, livestock are particularly at risk. Animals can die in a matter of hours if they ingest the plant. The plant has no antidote and has no known cure.

Water hemlock, or Cicuta douglasii, is found in North America. It is thought to be the most poisonous range plant in the continent. It can be found in all states, but is most prevalent in moist areas such as pastures, waterways, and cultivated fields.

The root of the water hemlock is known as Cicutoxin, and contains a toxic substance known as cicutoxin. Cicutoxin is a neurotoxin that is highly labile. It can be absorbed through the skin, lungs, and mucus membranes.

Water hemlock poisoning symptoms can be triggered by exposure to water, which is why the plant is so often mistaken for edible plants. The plant is not as dangerous as poison ivy, sumac, and poison oak, and it can be controlled by applying herbicides.

The best way to protect yourself and your family from poison hemlock is to wear gloves, masks, and rubber gloves. If you have any questions, you should contact your veterinarian or the local emergency department. They can help you determine whether you have a medical emergency or not.

Water hemlock is a biennial plant, and the root can be confused with wild parsnips. However, a small amount of root is easy to identify because of its bitter taste.

In the case of a dog, the symptoms of poisoning from water hemlock can include respiratory failure, convulsions, weakness, and respiratory paralysis. If you suspect your dog may have ingested the plant, you should seek immediate medical attention. Depending on the severity of the condition, your pet may require mechanical ventilation or diuretics.


Keeping your livestock safe from poison hemlock is important. This plant is poisonous to most classes of domestic animals, including cattle, sheep and goats. Various herbicides are available to help control this invasive plant.

Western waterhemlock (Poison hemlock), also known as wild parsnip, is one of the most poisonous plants in North America. It is easily identified by its bulbous root structure.

Its tubers exude a highly poisonous liquid. It is toxic to animals as well as humans. When exposed, the hemlock root’s toxins can cause seizures and even death. Its roots are also poisonous to horses.

To prevent water hemlock poisoning, the root must be burned. It is also important to pull the entire plant to remove its taproot. When removing the plant, avoid disturbing its soil.

Water hemlock is a member of the Apiaceae plant family. It grows in wet meadows, banks of streams and irrigation ditches. In higher elevations, it flowers. The tubers exude a highly poisonous substance, cicutoxin.

Western waterhemlock can be easily identified by its bulbous root structure. It grows from two to eight feet tall. It is usually found in wet meadows, banks and streams, but also thrives in irrigation ditches.

Western waterhemlock is a serious weed, causing livestock losses. It can be eliminated through burning or spraying. To avoid exposing its toxic roots, it is important to clear land by removing the entire plant.

Western waterhemlock has also been known to cause death in humans. In Tacoma, Washington, a woman died from eating the root of the plant in a salad. Its toxins can cause contact dermatitis and serious illness.

Western waterhemlock seeds are spread by animals and mud. They can remain viable in the soil for up to three years. The seeds can also be transported by water. The seed heads are green and poisonous. Cattle and sheep are the most susceptible domestic animals to poison hemlock, but goats and horses are also at risk.

When applying herbicides to control poison hemlock, it is important to follow the label’s restrictions. Herbicides are available to residential and commercial users. Depending on the number of plants in the infestation, it may be necessary to apply the herbicide several times.
