Cistus canadensis
Crocanthemum canadense · Frostweed, Canadian rock rose. · Plant · Cistaceae
Cistus is most appropriate for those who are frightened and stressed. Mental stress often aggravates their physical symptoms. Extremely sensitive to cold air, they tend to feel cold sensations all over the body. Their illnesses are generally affected by the seasons, becoming worse in winter.
Cistus is used mainly for frequent colds, tonsillitis, upper respiratory tract infections, chronic or recurrent sinusitis, and allergic rhinitis. Typical symptoms include thick, yellowy catarrh, a runny nose, and violent sneezing. The throat is dry and feels sore if even small amounts of cold air are inhaled.
Another key symptom associated with Cistus is glandular swelling and hardening, particularly in the neck, and possibly with concurrent respiratory symptoms. It may be due to infection or even cancer.

Characteristics
Cistus is a very ancient remedy for scrofulous affections, and also in scorbutic states and gangrenous ulcerations. The provings and homœopathic uses confirm its suitability in these respects and bring out clearer indications. It is most suited to scrofulous subjects who are very sensitive to cold air. "Sensitive to cold air" runs through the pathogenesis and also feelings of coldness, of which its peculiar property of favouring the formation of ice about its roots in early winter is strangely suggestive. Cold feelings: in larynx; in abdomen. "Inhaling the slightest cold air causes sore-throat, which he has not when inhaling in a warm room." Inhaled air feels cool. Cold breath. …
