If you use it for oil pulling, definitely spit it out (into the trash, since it can harden in the sink).
You can use it vaginally and it’ll help with localized yeast infections, but I don’t believe it’ll have an impact on your gut-based candida.
You can melt it or cook with it. I cook with it at almost every meal. Try melting some in a pan over a low flame, then add chopped up garlic to it for a few minutes until the garlic cooks a little. You can pour the oil and garlic over your veggies for flavoring along with sea salt and pepper.
