Dr. Eric Berg quoted observations made by Dr. Anthony Cardillo, who recounted his success in significantly improving the medical conditions of coronavirus patients after giving them anti-malaria medication (hydroxychloroquine) along with the zinc supplement.

According to Dr. Berg, the anti-malarial medication allows zinc to infiltrate cells and prevent the coronavirus from multiplying.

He emphasized that the drug should not be taken by healthy individuals or with the absence of a doctor's prescription. He also noted that many coronavirus patients had been observed to have zinc deficiencies.
