National Security has started an operation to remove a drink sold in Kumasi.
This drink is popular and is believed to be a cleansing tonic.
Tests done by the Department of Pharmacology at KNUST showed dangerous substances in the drink.
These substances were so strong that they killed rats within 24 hours.
The drink is known in Hausa as Madara Sukudai.
Experts suggest it may cause serious harm to kidneys and livers.
Authorities are taking steps to protect the public from this harmful concoction.
Further investigations are ongoing to understand the full extent of the ingredients and their effects.
