Ragwort is a highly toxic plant that killed 500 horses last year in the UK alone. The plant once consumed leaves the digestive tract into the liver where it produces toxins known as pyrrolizidine alkaloids which destroys the liver.
Symptoms include:weight loss, photosensitive dermatitis in the non-pigmented skin-lethargy or change in behavior-may wander and stagger-may stand with head against a wall-become blind-difficult breathing.
Unfortunately, symptoms may not materialize until most of the liver has already been destroyed, at which time it may be too late. There is no definitive test that can tell, but through symptoms may eliminate other things until the vet has a diagnosis.
A horse typically will not eat Ragwort when it is fresh as it taste bitter. However when it is dried it has no flavor and horses will consume it, either on pasture or in hay. Ragwort is toxic and causes cirrhosis of the liver. It can take as little as 3% of the horses body weight in ragwort to cause destruction of the liver. Ragwort has many other names, but they all fall under the scientific names of Jacobaea Vulgaris , and syn. Senecio jacobaea. Common names for Ragwort include: Benweed, st. James-wort,ragweed, tansy ragwort, staggerwort, cushag, mare's fart,cankerwort, dog standard , stammerwort, and stinking nanny/willy/ninny. You can prevent ragwort poisoning by hand weeding any area where a horse may have contact with ragwort, ensure you pull up the complete root system or it will regrow.
I think they are Ragwort, Deadly nightshade and Oak. Deadly Nightshade and Ragwort are both deadly to humans as well as cattle sheep and other grass eating animals. Horses will eat ragwort only as a last resort to food. Dig it out ASAP because when it dies the Ragwort looses its rank smell.

some of the common symptoms to look for are lying down if your horse does not typically lie down, not eating or pooping. These are they main ones. If you see these them you should get your horse up and walking and listen to his stomach, if you can hear gurling then he is probs not colicing but if you cannot than keep him walking and call a vet and if you have banamine give him some while waiting for the vet. Hope this helps!
