Sheep-Lice (HOUND'S TONGUE) Side Effects & Safety
Hound's tongue is UNSAFE and poisonous. There’s a lot of concern about using hound’s tongue as medicine, because it contains chemicals called hepatotoxic pyrrolizidine alkaloids (PAs), which may block blood flow in the veins and cause liver damage. Hepatotoxic PAs might also cause cancer and birth defects. Hound’s tongue preparations that are not certified and labeled “hepatotoxic PA-free” are considered UNSAFE.
It’s also UNSAFE to apply hound’s tongue to broken skin. The dangerous chemicals in hound’s tongue can be absorbed quickly through broken skin and can lead to dangerous body-wide toxicity. Steer clear of skin products that aren’t certified and labeled “hepatotoxic PA-free.” There isn’t enough information to know if it’s safe to apply certified hepatotoxic PA-free hound’s tongue to unbroken skin. It’s best to avoid use.

Hound's tongue isn't safe for anyone to use. Some people may be extra sensitive to the toxic effects and should be particularly careful to avoid use.Pregnancy and breast-feeding: It’s UNSAFE to use hound’s tongue preparations that might contain hepatotoxic PAs during pregnancy. These products might cause birth defects and liver damage.
It’s also UNSAFE to use hound’s tongue preparations that might contain hepatotoxic PAs if you are breast-feeding. These chemicals can pass into breast-milk and might harm the nursing infant.
It’s not known whether products that are certified hepatotoxic PA-free are safe to use during pregnancy or breast-feeding. Stay in the safe side and avoid using any hound’s tongue preparation if you are pregnant or breast-feeding.
