Both points sit on the palmar surface of the forearm, in a narrow space beside the tendon of flexor carpi radialis, where the median nerve and the radial artery lie close by, and that is the whole of the safety issue. Do not needle this point, do not press a hard object into it, and do not apply moxa or heat to it yourself: the front of the forearm has little padding over the tendons and vessels, and a haematoma or infection there can restrict the hand. The second issue is the reason people look this point up. Blood in the stool, a lump that protrudes, a change in bowel habit that does not settle, or bleeding with weight loss are things that need an examination, because colorectal cancer and inflammatory bowel disease present in exactly this way and are found by looking, not by treating a point on the arm. A point on the forearm cannot stand in for that examination, and delaying it is the one outcome this entry wants to prevent. There is nothing a reader should self-administer at this site.
