There are lot of research on ALS but felt that will take an decade to actually treat this disorder. The treatment such as StemCell is on the way, In china they claim to solve the treatment through medical and also via herbs. TCM treatment is for the herbs but no guarantee... Secondly Dr hongyun huang is involved with OEG Cells Procedure (not Stem Cell),

[OEC :OEG cells come from nasal mucosa, which migrate to the olfactory nerve through the cribiform plate to the olfactory bulb. The olfactory nerve is the only part of the central nervous system that is known to regenerate continuously throughout adult life. This ability has been attributed to the presence of olfactory ensheathing cells (OECs)]

But this process is costly, and also not guaranteed. The process is under observation.
