Licorice that has the active ingredient of glycyrrhiza can have serious side effects. Another type of licorice, called DGL or deglycyrrhizinated licorice, doesn't seem to have the same side effects and is sometimes used to treat peptic ulcers, canker sores, and reflux (GERD).
Myelodysplastic syndromes (MDS) can be associated with systemic or autoimmune diseases. Vasculitides (leucocytoclastic, periarteritis nodosa, micropolyangeitis, Wegener's granulomatosis), relapsing polychondritis, and Sweet's syndrome are the most commonly reported.
Other autoimmune disorders of the myelin sheath include transverse myelitis, which involves an attack on the spinal cord, and acute disseminated encephalomyelitis, or ADEM, which involves both the brain and spinal cord.
