Wisbroek Milk Thistle Oil

Before: Avis Cibum Milk Thistle Oil

Wisbroek Milk Thistle Oil is a source of vitamins, fatty acids and sylimarin. It supports birds with liver problems, but also with strengthening after illness.


How does it work?

Milk thistle is known for its healing effects. The black seeds of the dead plant are often fed to birds such as bullfinches and hookbills. For smaller birds, the seeds are often difficult to peel. By using it as an oil, it is accessible to all birds.

Milk Thistle Oil is rich in vitamin E, sylimarin and unsaturated fatty acids. Sylimarin is a natural ingredient to support liver problems. It also supports after illness, pneumonia, jaundice and liver disorders.

Advice for use

Wisbroek Milk Thistle Oil can be mixed with the bird feed. Mix 5 ml. oil by 1 kg seed or soft food.

Tip from Mr. U:

Pour Wisbroek Milk Thistle Oil over food animals such as insects. In this way, insect-eating birds ingest the oil with their food.

Who is it suitable for?

Wisbroek Milk Thistle Oil is a supplement for all birds, such as insect-eating birds and psittacines.
