Characteristics
*Nat-a. has been very extensively proved, notably by Imbert Gourbeyre. The irritating arsenical effects preponderate. The principal clinical use of *Nat-a. has been in diphtheria (dark purple throat, great swelling, much prostration, *not much pain) and in affections of the eyes and nose, and root of nose.

Pain at root of nose. Feeling as if the body were compressed by thumb and finger. Feeling of lump in throat, of blow on testicle, as if smoke inhaled into lungs. Emaciation. Oedema. Pain between scapulae better bending forward. There is the restlessness of *Arsen, and the thirst, and also the chilliness, with the hot head and headache worse by heat. The symptoms are worse on pressure. Worse By motion, jarring, least exertion. Interscapular pain better bending forward. Worse On moving is very prominent throughout the proving, also worse during the day. Nasal obstruction and chilliness worse at night.
