Ricin /ˈraɪsɪn/ is a highly toxic, naturally occurring lectin (a carbohydrate-binding protein) produced in the seeds of the castor oil plant Ricinus communis. A dose of purified ricin powder the size of a few grains of table salt can kill an adult human.[1] The median lethal dose (LD50) of ricin is around 22 micrograms per kilogram of body weight (1.78 mg for an average adult, around 1⁄228 of a standard aspirin tablet/0.4 g gross) in humans if exposure is from injection or inhalation.[2] Oral exposure to ricin is far less toxic, and an estimated lethal dose in humans is approximately 1 milligram per kilogram.[
Hydrangeas are nice - you can tamper with the colours too by putting nails and stuff into the soil to alter the PH levels (or something like that). I used to hate Hydrangeas - now I think they do look lovely and fill out nicely.
