WHO Africa director Matshidiso Moeti made the call on Thursday.
“We have offered to support the design of a study to look into this product,” Moeti said.
The herbal remedy, called “COVID Organics” and prepared by the Malagasy Institute for Applied Research, is made out of artemisia, a plant cultivated on the Indian Ocean island.
Children returning to school have been required to take it.
“This plant strengthens immunity and protects against numerous viruses and fever and especially lung diseases,” Rajoelina said.
Meanwhile, the institute’s director general, Charles Andrianjara has spoken only of the remedy being preventative.
The remedy is being distributed for free to vulnerable people and sold commercially.
In early May, Tanzanian President John Magufuli announced that he had placed an order for “COVID Organics.” (dpa/NAN)
