Cleistocactus strausii
As a houseplant, the Silver Torch cactus is an easy to take care of so long as over-watering is avoided. To naturally simulate the porous effects of the sand in its native habitat, it's important to ensure that excess water will not pool in the soil, causing the roots to become water logged.
This plant’s native habitat does not have winter, but when temperatures drop to the low twenties, it can exhibit signs of tip frost. 
The Silver Torch cactus is most susceptible to 
mealybugs 
and spider mite.
Coconut water
One health risk arising from excessive consumption of coconut water is an overabundance of potassium in the blood (hyperkalemia), inducing acute kidney failure, heart arrhythmia, loss of consciousness and eventually death. Hyperkalemia and loss of consciousness after the consumption of several liters of coconut water were reported only as a clinical case study in association with one individual's use of a commercial product following physical exertion. However, the levels of potassium in each 100 ml serving of unprocessed coconut water are not very significant (2–7% of the DV).
