Before modern-day toothpaste was created, pharmacists mixed and sold tooth cream or powder. Early tooth powders were made from something abrasive, like talc or crushed seashells, mixed with essential oils, such as eucalyptus or camphor, thought to fight germs. Their flavors came from oils of cinnamon, clove, rose or peppermint. Many contained other chemicals such as ammonia, chlorophyll and penicillin. These ingredients fight the acid-producing bacteria that can cause tooth decay and bad breath.

Penicillin in early toothpaste? Wouldn’t people have noted infections clearing up?

    I(f they didn’t, the monumental case of the shits they’d getting would. Penicillin plays havoc with your intestinal flora.

  3. Weren’t antacid tablets inspired by noticing that plasterers with upset stomaches would lick their fingers, long before the medicinal effects of calcium carbonate were properly described.

    The runs aren’t universal, I’ve only encountered two strains of Penicillin that give me the runs, other anti-biotics don’t. Conversely every anti-biotic my mother takes give her the runs

  5. A few times I’ve had penicillin, never given me problems. Perhaps not affecting my gut bacteria.

    Saying that, if it did have such an impact on people then it would have quickly been stopped from being used.
    The runs have caused considerable harm and death in those weakened by injury.

    My wife has been on penicillin for over a decade, daily dose as a preventative. Normally any drug has an impact on her, no negative impact from that daily dose.
    Good positive impacts, she’s still alive.

    The choice is die from infection vs maybe die from the runs if you don’t eat/drink enough – take the penicillin wins

  7. OT again

    Watching C4 F1: ads for Scottish Water in breaks several times – not selling/recruiting anything

    WTF: State owned monopoly advertising – why, oh why are SNP wasting money on making and broadcasting an ad, more so as they’re high cost slots.

  8. “Academic rigor and journalistic flair”


    A “not for profit” being transfused funding from academia (your taxes)

    Nice little earner well away from the hurley burley of having to produce content that attracts actual readers that either pay for content or are valued by advertisers.

    Vanity on a stick

    How else are the party faithful to be awarded other than sinecures in non-jobs such as PR and marketing going to justify their existence, self-importance and standing within the Party?

  10. There are around 300 species of penicillin. I have heard of anyone being cured of an infection by eating brie, gorgonzola or stilton

    I forgot to mention: no domestic water meters* in Scotland, thus not advertising “buy more water” nor “save water”

    * One may switch to metered water, but the annual “standing charge” is more than having unmetered water.

  12. I was required to have a water meter installed as I’ve got a pool. Saved me a few hundred a year, because we’re a 2-person family, so no big wash twice a day 🙂
