The juice from Celandine has a strong skin-irritating effect and was used in folk medicine to remove warts and treat eczema and ringworm. Today the plant is mainly used in the production of yellow dye for wool.

The whole plant is toxic in moderate doses as it contains a range of isoquinoline alkaloids but there are numerous therapeutic uses when used at the correct dosage.[1] The main alkaloid present in the herb and root is coptisine. (Wikipedia)
