Trifolium pratense
Plant · Fabaceae
Trifolium pratense suits patients with prominent salivary gland congestion (as in mumps or pre-mumps states) combined with respiratory irritation producing dry hacking cough, hoarseness, and a sensation of breathing hot air. There is a cancerous diathesis with general congestive tendency. It retards progress of cancerous tumors before ulceration and has a role in whooping cough and measles cough.
Key symptoms
- Marked ptyalism; profuse salivation; sensation as if mumps coming on
- Dry tickling hacking cough from pharyngeal and tracheal irritation
- Sensation as if breathing hot air; lungs feel full of blood
- Choking and hoarseness at night with cough; stiff neck
- Cramps in sternomastoid muscles better from heat and friction
- Persistent headache on waking in morning; dullness in anterior brain
- Sleep unrefreshing; confused on waking
- Whooping cough with paroxysms worse at night
- Cancerous diathesis; retards progress of tumors before ulceration
Worse (aggravation)
- In close room
- After sleep
- At night (cough)
Better (amelioration)
- In open air
- Heat and friction (stiff neck and sternomastoid cramps)
