After the last watering, wait two or three weeks for the area to dry and settle before attempting to install plants. This can cause pain, stiffness and decreased physical function. According to Martha Raidl, University of Idaho extension nutrition specialist, glucoseamine is one of the components of cartilage. A three-year study of 200 Belgian subjects with osteoarthritis who took 1,500 mg of glucoseamine sulfate each day showed that they had less pain, stiffness and cartilage deterioration. The glucoseamine became effective within four weeks of taking it, Raidl says.
Some side effects can occur, including headaches, nausea, leg pain, itching and drowsiness.
