Those for whom Asclepias tub. is most appropriate tend to be depressed, languid, and unable to concentrate.
Asclepias tub. is associated particularly with rheumatic pain and catarrh, both tending to arise in damp weather. The rheumatic pain is characterized by stitchlike pains in the muscles and joints. The remedy may be prescribed for many forms of respiratory inflammation, such as bronchitis, influenza, pleurisy, or other feverish conditions with a painful, dry, hacking cough.
