When regrowing an entire bone, Harry Potter described the sensation as having large splinters lodged in his arm. The potion comes in a large bottle and smokes as it is dispensed. Swallowing it burns the throat, and, according to Harry, it tasted awful and he spat it out when he first tried it. For a magical treatment, Skele-Gro is surprisingly slow working when regrowing whole bones, taking most of the night to regrow the bones in Harry's arm. However, since he required thirty-three bones to be regrown outright, it is likely that its effects vary with the amount required to be healed or regrown.
