Brief summary: This study will examine the effectiveness of Cistanche Total Glycosides(CTG) in treating patients with amyotrophic lateral sclerosis (ALS) - a fatal neurological degenerative disease that causes adult-onset, progressive motor neurons loss in the spinal cord, brain stem and motor cortex. Patients develop progressive wasting and weakness of both upper and lower limbs, bulbar and respiratory muscles. Usually death from respiratory failure typically is within 3-5 years of diagnosis. Although there are various treatments for ALS, riluzole is the only approved treatment to delay the disease progression. Cistanche Total Glycosides is an approved drug that has protective effects. It acts anti-apoptosis by activating several protective pathways, stimulates neuronal differentiation of adult neural stem cells in the brain, and improves long-term recovery. CTG is a highly attractive candidate for the treatment of neurodegenerative conditions such as ALS.

Patients 18 to 65 years of age who have had mild to moderately severe ALS for 0.5 to 2 years of duration may be eligible for this study. Candidates will be screened with a medical history and possible review of medical records, physical examination, blood test, urine and stool analyses, electrocardiogram, electrophysiological examination, neurological imaging and, for women, a pregnancy test.

Participants will have drug therapy according to randomized number. One group receives CTG while other group receives placebo. For the procedure, patients are given a medication to lessen anxiety and any discomfort. Patients receive drugs for 9 months. The CTG dosage is 1.8g/day. Physical examination and interview, Appel ALS scale and ALS-Functional Rating Scale will be done in 28 days and 3, 6, 9months. Electrophysiological examination will be tested per 3 months. Blood samples will be collected on treat28 days and 3, 6, 9months.
