The drugs help to block involuntary movements of the muscles associated with these diseases. They also balance the production of dopamine and acetylcholine in the body. Anticholinergics can also be used to treat certain types of toxic poisoning, and are sometimes used as an aid to anesthesia.
1 The following common household items can be used to remove blood stains: baking soda, white, unseasoned meat tenderizer, salt, or hydrogen peroxide along with cold water.  For baking soda and meat tenderizer, make a paste using cold water and apply to the stain. Let it set for 15-30 minutes and rinse with cold water.
Never use hot water because it cooks the protein into the fibers making the stain harder to remove. To flush away the blood stain, hold the fabric under a cold water faucet with the wrong side of the fabric directly under the water stream. The force of the water will flush the blood stain out of the fibers.
