The oil content of thuja is what has shown powerful immunostimulating activity. Many clinical in vitro and in vivo studies have been carried out. Trials have shown it to have an HIV – 1activity, spleen cell proliferation, cytokine induction, antibody production, increased leukocyte production, increased immune response, proven immunomodulatory efficacy and supportive effects for the common cold. Other studies have shown it to have supportive effects when on antibiotic treatment.
Thuja acts as an antiviral and has great immune stimulating potential. It is known to stimulate macrophages and other immunocompetent cells. Its main action is due to its stimulating volatile oil. Thuja will help treat disorders of the mucous linings of the bronchial tubes. It is valuable in ulcerative forms of sore throats and for fetid secretions.
It has a specific reflex action on the uterus and can be used also in incontinence, where there is a lack of muscle tone, as it strengthens the sphincter of the bladder. It can be used for the elderly and the young and can prove beneficial for bedwetting. It is valuable where there is dribbling of the urine or dribbling when coughing or sneezing. It could be used with men with chronic prostatitis as it relieves the weakness at the neck of the bladder. It is indicated in the treatment of psoriasis and rheumatism.
Externally it is commonly known for the treatment of warts, as well as thrush and ringworm.
Acting as an alterative it helps clean the blood. It is known to help reduce ‘lumps and bumps’ and any abnormal growths on the skin or mucous membranes.
David Hoffman describes the use of this herb thus: “Thuja is given internally for cancer and for the pains of cancer it is applied externally, when possible, occasionally with good results. Thuja certainly exercises a direct influence upon the glandular structures and function. In what manner this influence is exercised is unknown, but in any disease that involves the gland, this remedy must be considered, and if there are no contraindications it can be tried and in many cases as with the ductless glands, it seems to act in a direct manner.
