5. Individuals who have visual and hearing abilities to perform the trial; who are able to understand the words and sentences necessary to evaluate the efficacy and safety, as well as the investigator's instructions; and who are able to communicate (such as gestures, writing, speaking, etc.)
6. Voluntary written informed consent to study participation

Exclusion Criteria:

1. Presence of motor function impairment, which is caused by previous stroke except acute ischemic stroke occurring within 14 days of screening (A subject with previous history of stroke may participate if he/she showed no motor function impairment and the K-mRS score was ≤1 (0-1))
2. Diagnosis of and current treatment for degenerative neurological diseases, e.g., Parkinson's disease and Alzheimer's disease
3. Current treatment with amphetamines, selective serotonin reuptake inhibitors, or antipsychotics
4. Presence of brain diseases, such as brain tumor, traumatic brain damage, arteriovenous malformation, or moyamoya disease, or ischemic stroke caused by these diseases
5. Impaired ability to walk upright due to other illness prior to screening
6. Unstable vital signs at screening based on the judgment of the investigator e.g., systolic blood pressure ≥ 170mmHg despite antihypertensive treatment or other symptoms such as hyperthermia, tachycardia, or hyperventilation
7. Diagnosis of liver diseases prior to screening, such as hepatitis and liver cirrhosis, or current treatment for these diseases
8. Continuous treatment with potentially hepatotoxic drugs e.g., current treatment with propylthiouracil, ketoconazole, isoniazid, valproic acid, phenytoin, etc. that may induce acute hepatotoxicity

9. Severe, New York Heart Association (NYHA) Class III or higher heart failure at screening [NYHA Classes of heart failure] Class I: patients with no limitation of activities; they suffer no symptoms from ordinary activities.

   Class II: patients with slight, mild limitation of activity; they are comfortable with rest or with mild exertion.

   Class III: patients with marked limitation of activity; they are comfortable only at rest.

   Class IV: patients who should be at complete rest, confined to bed or chair; any physical activity brings on.

10. Diagnosis of or treatment for cancer within 6 months of screening or presence of recurrent or metastatic cancer
11. Treatment with or intake of traditional oriental medicine (herbal medicine) or health functional foods containing potentially hepatotoxic plants, such as Germander (Teucrium chamaedrys, Teucrium polium), toothed clubmoss (Lycopodium serratum), or celandine (Chelidonium majus), within 4 weeks prior to study participation
12. Treatment with or intake of traditional Korean medicine containing pueraria root and/or scutellaria root or other drugs or health functional foods containing their respective index components, i.e. puerarin and baicalin, within 4 weeks prior to study participation

13. Hematologic findings as follows

    ① Increased serum aspartate or alanine aminotransferase (AST/ALT) levels ≥ 1.5 x site specific upper limit of normal in laboratory test

    ② Decreased hemoglobin (Hb) level (Hb< 10 g/dl), decreased platelet (PLT) level (PLT< 100,000/mm3), or hematocrit (Hct) level < 25% in whole blood count test.

    ③ Increased serum creatinine (Cr) level (Cr > 2.0 mg/dl) in laboratory test or patient on dialysis

14. Pregnant or lactating women A woman of childbearing potential can participate in the study only if non-pregnancy is confirmed.

    Subjects must use a double barrier method or must have been surgically sterilized.

15. Previous participation in a clinical study for another drug within 3 months of screening. A subject who participated in an observational study that did not involve drug treatment may participate in this study.
16. Individuals who are considered by the investigator to be inadequate for study participation due to other reasons.
