Just thought I'd share this with you for sake of interest. Photo is of sap I got on my palm off Aloe broomii - Imagine what you'd look like if you rubbed the juice of this Aloe into your sunburn! :} It does only last about one day and fades pretty quick.. I guess it still has a beneficial use as a dye? According to this site (http://www.plantzafrica.com/) it has these uses: To kill ticks and used as a dip for livestock, a disinfectant and a remedy for sheep.
