The rattlesnake is distinctive because of its tail, which makes a rattling sound when it is about to strike. The homeopathic remedy was first proved by Dr. Hering in 1837 and is used today for a range of serious illnesses. The Latin name for the rattlesnake derives from the AGreekkrotalon, meaning "rattle" or "castanet." This is due to the distinctive rattling sound made by the snake's tail, which vibrates at 50 beats per second as the creature prepares to strike its prey. The remedy, proved by the US homeopath Dr. Constantine Hering in 1837, is prescribed primarily for a range of serious disorders, including hemorrhaging, angina, strokes, and infection. Those who respond best to Crotalus tend to be sluggish and melancholic. They are prone to forgetfulness, al;ld may lose their way in their own neighborhood, or even f,orget the names of close friends. An aversion to family members is typical of these people, and a desire for meat, especially pork, is common. Crotalus is considered to help stop bleeding from any orifice, making it highly useful for hemorrhaging. It is given following the onset of a state of total collapse, which may be due to a severe septic state, a stroke, or a heart attack. In addition, it may help cases of delirium, throat infection, or retinal hemorrhage. Venom "milked" from live snakes is used to make antivenins. which trigger production of antibodies that neutralize the poison from a snakebite. Venom obtained from a live snake by "milking" it is dropped onto lactose sugar.The resulting mixture is then triturated. Crotalus hor. helps stop bleeding from any orifice, especially when it is slow and the blood is dark, thin, and does not clot. The remedy is used for jaundice, sepsis, and total collapse.

Sometimes it is given for swelling in the whole body; for example in liver failure and blood poisoning. It can also be helpful for alcoholism. Bleeding - Copious bleeding from any orifice. The remedy is especially effective for slow bleeding, or for thin, dark blood that does not clot well. It may seem as though blood is present in the Perspiration or tears.

Crotalus is used for septicemia with hemorrhaging where the breakdown of red blood cells is so great that the liver becomes overwhelmed, leading to the onset of serious conditions such as jaundice.
