Precocious puberty impacts the physical and psychological health of children from the onset of the condition and can even persist throughout their lifetime.The effects are not limited to the affected children but also extend to their families and society，posing a significant hidden danger.The incidence of precocious puberty is rising annually，indicating a trend towards becoming a common condition.Physical constitution is characterized by individuality，relative stability，and variability.The identification of physical constitution has a long history and can assess imbalances and functional differences in the organs，essential qi，yin，and yang of the human body.Traditional Chinese medicine(TCM) has unique advantages in identifying children's physical constitution.Through clinical practice over the ages，TCM practitioners have classified the physical constitution of children with precocious puberty mainly into three types：yin deficiency，phlegm-dampness，and qi stagnation.However，this classification is not comprehensive，and clinical observations and related research have found that children with a balanced constitution can also develop this condition.Currently，research on the TCM constitution of children with precocious puberty has made significant progress but has not yet reached a systematic and unified approach.
