Brief Summary

Lycium barbarum, a traditional Chinese herbal medicine, is a commonly used herb in the traditional Chinese pharmacopoeia . Its main active ingredient, lycium barbarum polysaccharide (LBP), is reported to have neuroprotective effects. Animal studies suggested that LBP has neuroprotective effect on optic ganglion cells. In animal models of depression, LBP can improve depressive symptom by improving synaptic plasticity. However, its clinical effect remains to be studied. We will conduct a 6-week double-blind, randomized, placebo-con-trolled trial in people with subthreshold depression.The purpose of this clinical trial is to investigate the efficacy of LBP in people with subthreshold depression.

Outcome Measures

Primary Outcomes (1)

  • Mean changes from baseline in the 21-item Hamilton Depression Rating Scale (24-HAMD)

    The 24-item HAM-D scale is widely used to assess the severity of depression.The scale is a 21-item assessment used to measure depression severity. Items were rated on a scale from 0 (symptoms not present) to a maximum of 2 to 4 (symptom extremely severe) for a total score ranging from 0 (not at all depressed) to 64 (severely depressed).

    6 weeks

Secondary Outcomes (4)

  • Changes in The Screen for Child Anxiety Related Disorders (SCARED)

    4 and 6 weeks

  • Changes in sleep quality

    6 weeks

  • Depression severity as measured by BDI2 and Kessler Scale (K10)

    6 weeks

  • Mean change from baseline in the Beck Depression Inventory-II (BDI-2)total scores

    6 week

Other Outcomes (1)

  • Treatment-emergent symptom side effect (TESS) scale.

    4 and 6 weeks
