Nystatin powder has been fighting Candida infections for a long time, and the evidence says it's still pulling its weight. In one striking example, classic topical nystatin powder at 6,000,000 units per gram eradicated severe angioinvasive fungal infections in burn wounds across 4 patients, clearing both superficial and deep disease without impairing wound healing. That's a drug applied directly to some of the most vulnerable tissue imaginable, doing its job and getting out of the way.
The reason nystatin stays relevant is also the reason it frustrates researchers: it barely absorbs into anything. Your gut doesn't take it up. Your skin doesn't take it up. That makes systemic toxicity very low, but it also means the powder itself dissolves poorly in water, doesn't penetrate deeply, and needs frequent reapplication. Modern pharmaceutical science is trying to solve exactly that problem.

Most people prescribed nystatin for oral thrush get the suspension, that yellow liquid you swish around and swallow. But the research consistently shows that lozenges and pastilles outperform the suspension, and that how long you use nystatin matters just as much as which form you choose. If you have been swishing for a few days without results, the problem might not be the drug. It might be the delivery method.
Oral nystatin is a topical antifungal, meaning it works right where you put it rather than traveling through your bloodstream. It is not absorbed from the GI tract at all. That is both its biggest advantage (very few systemic side effects) and its limitation (it only works while it is in contact with the infection).

Herpes on the tongue usually means painful blisters or ulcers that heal with antiviral medication in one to two weeks. That's the straightforward version. The less obvious version: in certain people, tongue herpes can show up as deep fissures, white plaques, or swollen masses that look remarkably like oral cancer. Research consistently links these atypical presentations to immunosuppression, and missing them has real consequences.
Most tongue herpes is caused by HSV-1. Less commonly, HSV-2 or herpes zoster (the shingles virus) is responsible. But the virus matters less than what it does on your tongue and how your immune system shapes the outcome.

Hydroxyapatite (HAP) toothpaste performs about as well as fluoride toothpaste for preventing cavities in clinical trials, and it actually outperforms fluoride for tooth sensitivity. That's a genuinely interesting finding. But the strength of that cavity evidence isn't as solid as you might hope, and the details matter if you're trying to decide whether to make a switch.
A 2024 meta-analysis pooling 18 clinical and in-situ studies found HAP toothpastes were about 2.5 times more effective than placebo at reducing caries, with a non-significant trend actually favoring HAP over fluoride. "Non-significant" is the key word there: statistically, the two performed similarly. For sensitivity, though, the story is clearer, and HAP has a real edge.

Most HPV-related bumps on the lips are caused by low-risk virus types and won't progress to cancer. They typically show up as small, soft, painless growths with a papillary or cauliflower-like surface, white or pink in color, slow to grow, and responsive to straightforward surgical removal. The complication is that they can closely resemble things that are more serious, so an eyeball assessment alone isn't enough.
Lip bumps also have plenty of non-HPV explanations: cold sores, trauma, irritation, or unrelated benign growths. A dentist, oral surgeon, or dermatologist is the right person to sort it out.
