Efficacy and Safety Morus Alba L. Extract on Improvement of Blood Flow

This study was a 12 weeks, randomized, double-blind, placebo-controlled human trial. Hundred subjects were randomly divided into Morus alba L. extract or a placebo group. Blood was collected and changes in blood circulation related indicators were observed.

• Morus Alba L. Extract (Dietary supplement): Morus Alba L. Extract 30 ml/day for 12 weeks.
• Placebo (Dietary supplement): Placebo 30 ml/day for 12 weeks.

Primary outcomes

• Changes of Reactive Hyperemia Index [12 weeks]: Reactive Hyperemia Index was measured in study visit 1(0 week) and visit 3(12 weeks).
• Changes of Platelet function assay [12 weeks]: The whole blood with anticoagulant (sodium citrate) is passed through the capillary and the membrane to assess the degree of platelet adhesion to this membrane and the degree of occlusion of the capillary.

Secondary outcomes

• Changes of blood flow indices: PAI-1, t-PA [12 weeks]: Blood flow indices(PAI-1, t-PA) were measured in study visit 1(0 week) and visit 3(12 weeks).
• Changes of Pulse wave [12 weeks]: Measured using a pulse wave measuring device (uBioClipTM; BiosenseCreative Co., Ltd., Seoul, Korea) and measured three times, the average value of the measured values is indicated.
• Changes of Oxidation stress index: Oxidized LDL [12 weeks]: Oxidation stress indices(Oxidized LDL) was measured in study visit 1(0 week) and visit 3(12 weeks).
• Changes of Lipid peroxidation index: MDA (Malondialdehyde) [12 weeks]: Lipid peroxidation index{MDA(Malondialdehyde)} was measured in study visit 1(0 week) and visit 3(12 weeks).
• Changes of Lipid metabolism indices: Total cholesterol, Triglyceride, LDL-C, HDL-C [12 weeks]: Lipid metabolism indices(Total cholesterol, Triglyceride, LDL-C, HDL-C) were measured in study screening and visit 3(12 weeks).
• Changes of Arteriosclerosis indices: Total cholesterol/HDL-C, LDL-C/HDL-C, Triglyceride/HDL-C, (Total cholesterol-HDL-C)/HDL-C [12 weeks]: It is calculated by the calculation formula using the lipid metabolism indicator test item.
