Answer:
1. Hydroxychloroquine is the healing agent 
2. Chloroquine does not have a hydroxyl group attached     
Explanation:               
 Chloroquine and  Hydroxy chloroquine have been in use for many decades for malaria treatment and prophylaxis.    
It was found that there was a high possibility of being poisoned when treatment of chloroquine was administered. In 1946 the hydroxyl group replaced the CH3₃  (methyl) group with an ⁻OH (hydroxyl) group as indicated by the attachment. Toxicity by chloroquine was reduced to 40% when the ⁻OH group was attached.
Later chloroquine was added to formulas that are used for cleaning pools and fish tanks.
Both of these chemicals should be used by following the guide lines and under medical supervision if taken for any illness.
