I have used a dusting of regular, cheap cinnamon powder (likely cassia) on wounds/rot spots on succulent plants to good effect... Of course I never had two (or 100) with the same problems at the same time to see how many would have recovered without treatment, no doubt some would have.. I have also used Chamomile tea as a pre-sowing drench for seed pots, and never had damping off, but I also have not had problems on untreated pots (all kept in sealed plastic bags post sowing)..
