Drosera rotundifolia
Sundew, common sundew, round-leaved sundew, red rot, youthwort, moorgrass. · Plant · Droseraceae
Drosera is usually prescribed to treat a deep, violent, spasmodic cough, especially whooping cough. Associated symptoms may include restlessness, anxiety, retching, vomiting, cold sweats, and nosebleeds. There may also be a feeling that there is a feather or crumb in the larynx, which triggers coughing. The voice is often toneless, hoarse, and deep.
There is some indication that Drosera may be helpful in treating behavioral problems, particularly in children. It is best suited to children who are restless, anxious, peevish, and distrustful. Their emotions seem unbalanced, and they often have difficulty concentrating. Their anxiety may increase when they are alone, and can be associated with a fear of ghosts.
Drosera may also be given for childhood growing pains, especially if they are accompanied by emotional imbalance. Symptoms may include stiff ankles and pains in the joints and bones, particularly affecting the hips and thighs.
