The name `Duimpie-snuif' literally means thumb-snuff; traditionally it is used as a snuff. The pulverised plant is also reported to be an hallucinogenic additive to tobac.co to be smoked. Or else it can simply be dried and powdered and used as a snuff. The dosage is small with approximately 50 milligrams of plant chewed producing a feeling of euphoria, which lasts for about 20 minutes; this is followed by sedation.

Success story :

`Planted some seeds and am having a good run with them got 7 to germinate out of 10 with the Sceletium tortuosum : `Kanna' Seed-pack, and 8 germinated out of 10 with the Silene capensis : `Undlela zimhlope' Seed-pack, and I got 6 out of 10 to germinate on the Pleiospilos bolusii - Duimpiesnuif.
These numbers are very good on any cactus/succulent as I can get chestnut oil and have to use another anti-fungus spray that isn't as gentle on the seeds and seedlings. The key here is the planting soil and temperature. The soil I use is 1 cup potting soil, 1 cup seedling mix, 1 cup coarse sand, 1 cup perilite and 1 cup small gravel well mixed.  I put the seed on top and spray with fungicide cover with a VERY thin lair of sand, gut them in a heated germinator and keep the temp around 80f and the humidity around 90%. After they germinate and have grown for about a month I move them into another germinator where very slowly I lower the humidity down to what is normal where I live (which is low about 40%) over 6 months time or longer if the plant
is having problems with the lower humidity.'
