Cognac must be double distilled in a copper pot still. Armagnac is distilled in alembic continuous still (alembic armagnacais) with the exception of a few producers who double distill it in the same way as Cognac.
What is nystatin? Nystatin is an antifungal medication that fights infections caused by fungus. Nystatin when taken by mouth is used to treat yeast infections in the mouth or stomach. Oral nystatin is not absorbed into your bloodstream and will not treat fungal infections in other parts of the body or on the skin.
Get emergency medical help if you have any of these signs of an allergic reaction: hives; difficulty breathing; swelling of your face, lips, tongue, or throat. Stop using nystatin topical and call your doctor at once if you have severe burning, itching, rash, pain, or other irritation where the medicine is applied. Less serious side effects may include mild itching or irritation. This is not a complete list of side effects and others may occur.
