We have used the ArtemiC Rescue and ArtemiC Support combo, and it worked well for us for both short and long covid. You can find out more by typing it in. For either covid or long covid: First I use ArtemiC Rescue, which is a pump spray, 5 pumps in the morning, and 5 pumps at night at least half an hour before eating. After 2 days the bottle is finished. Second I use ArtemiC Support, which is a pipette, 0.5ml in the mornings and 0.5ml at night at least one half hour before eating. After 30 days the bottle is finished. And hopefully you'll be well.
