Promising Homeopathic Treatment for Cancer – Thuja Occidentalis

One of my early and onging regimens to protect my body from the formation of a new tumor is alternating doses of two homeopathic remedies, twice a day. This was recommended to me by one of the leading world practitioners of alternate remedies based on my total profile.

The first is 2 drops of Phytolacca 200C followed 3 hours later by 2 drops of Thuja Occidentalis 30C taken in 2 tsp of filtered water, and repeated another time later in the day.  (Homeopathic tinctures need to be taken 15-20 mins. away from taking anything by mouth.)

The studies supporting this regimen are ongoing and rather impressive. Below is one such study focused on Thuja.

Homeopathy takes the whole person into consideration for appropriate treatment, and not the symptoms alone.

Crude ethanolic extract of Thuja occidentalis (Fam: Cupressaceae) is used as homeopathic mother tincture (TOΦ) to treat various ailments, particularly moles and tumors, and also used in various other systems of traditional medicine. Anti-proliferative and apoptosis-inducing properties of TOΦ and the thujone-rich fraction (TRF) separated from it have been evaluated for their possible anti-cancer potentials in the malignant melanoma cell line A375.

On initial trial both TOΦ and TRF showed maximum cytotoxic effect on A375 cell line while the other three principal fractions separated by chromatography had negligible or no such effect, because of which only TRF was further characterized and subjected to certain other assays for determining its precise anti-proliferative and apoptotic potentials.

Exposure of TRF of Thuja occidentalis to A375 cells in vitro showed more cytotoxic, anti-proliferative and apoptotic effects as compared with TOΦ, but had minimal growth inhibitory responses when exposed to normal cells (peripheral blood mononuclear cell).  Furthermore, both TOΦ and TRF also caused a significant decrease in cell viability, induced inter-nucleosomal DNA fragmentation, mitochondrial transmembrane potential collapse, increase in ROS generation, and release of cytochrome c and caspase-3 activation, all of which are closely related to the induction of apoptosis in A375 cells.

Thus, TRF showed and matched all the anti-cancer responses of TOΦ and could be the main bio-active fraction. The use of TOΦ in traditional medicines against tumors has, therefore, a scientific basis.


Thuja occidentalis (Fam: Cupressaceae), commonly known as Arbor vitae or white cedar, is an ornamental tree grown in Europe [1]. It is used as a medicinal plant in various forms of traditional medicines like folk medicine, homeopathy, and so forth, for treatment of bronchial catarrh, enuresis, cystitis, psoriasis, uterine carcinomas, amenorrhea and rheumatism [25]. In homeopathy, the crude ethanolic extract of T. occidentalis is used as mother tincture (TOΦ).

Thuja is also occasionally used for treating diseases of skin, blood, gastrointestinal tract, kidney, brain, warty excrescences, spongy tumors, and so forth, and claimed to have pronounced remedial effects.

The extract has been reported to enhance the antibody response to sheep blood cells [6]. Protective effect of T. occidentalis has also been reported against radiation-induced toxicity in mice [7]. Ameliorative effect of T. occidentalis has also been suggested in preventing congestive heart disease [8]. Therefore, it gained attention of pharmacologists to study the major constituents of the dried herbal substances of T. occidentalis [911].

The major components found in extracts of all varieties of T. occidentalis comprise essential oil (1.4–4%) as the principal constituent.

In homeopathic literature [13], TOΦ has been reported to be effective against various forms of skin diseases, particularly in the treatment of moles and papillomas.

Homeopathic TOΦ has been reported earlier to have cytotoxic effect in Dalton’s lymphoma ascites (DLA), Ehrlich ascites carcinoma (EAC), and lung carcinoma L929 [14]. Dubey and Batra also reported hepato-protective activities [15] and antioxidant activity [16] of T. occidentalis in CCL4-treated liver damage in rats.

However, to the best of our knowledge, anti-cancer potentials of TOΦ or any of its major fractions had not been tested earlier in skin cancer cell line A375 by utilizing some widely acceptable parameters of study.

Thus, the hypotheses to be tested were:

(i)              whether TOΦ and all chromatographically separated fractions had potential anti-cancer effects in A375 cells;

(ii)            if any fraction could be demarcated as the most biologically active one;

(iii)          if, it is possible, to chemically characterize this fraction;

(iv)          whether the cytotoxic, anti-proliferative and apoptotic effects of the fraction, vis-à-vis TOΦ, could be compared with focus on its possible mechanism of action; and

(v)            if it is possible to assess the overall anti-cancer potentials of TOΦ in relation to its preferential cytotoxic effect over normal cells, by analyzing results of different relevant assays including the possible signaling pathways.


Results of the present study would indicate that the homeopathic drug T. occidentalis Φ had four chromatographically separated fractions of which the thujone-rich fraction was found to be the most bioactive (anti-cancer, pro-apoptotic) component. Unfortunately, despite our best effort, the oily nature of this fraction did not allow us to purify it to 100%, for which we were able to perform only mass spectrometry of TRF.

Anti-cancer activity of the alcoholic extract of T. occidentalis had earlier been reported by Sunila and Kuttan [14] from their in vivo studies in rats. In our present in vitro study involving several protocols, we confirm the pro-apoptotic and anti-cancer potential of T. occidentalis mother tincture. Additionally, it was revealed that the thujone-rich component was possibly the key bioactive compound showing its promising anti-cancer potentials in the skin cancer cell line A375, a fact which had not earlier been reported.

We determined the optimum dose through a range finding trial. The result revealed that the 220.18 μg mL–1 of TOΦ could produce 50% cell death in A375 while that dose was relatively non-toxic to PBMC. Correspondingly, of the three doses of 50, 100, 200 μg mL–1 of TRF used, 200 μg mL–1 TRF showed the maximum effect surpassing the effect of treatment with the TOΦ as revealed from the result of the several protocols.

Abstract:The use of ultra-diluted natural products in the management of disease and treatment of cancer has generated a lot of interest and controversy. We conducted an in vitro study to determine if products prescribed by a clinic in India have any effect on breast cancer cell lines. We studied four ultra-diluted remedies (Carcinosin, Phytolacca, Conium and Thuja) against two human breast adenocarcinoma cell lines (MCF-7 and MDA-MB-231) and a cell line derived from immortalized normal human mammary epithelial cells. The remedies exerted preferential cytotoxic effects against the two breast cancer cell lines, causing cell cycle delay/arrest and apoptosis.These effects were accompanied by altered expression of the cell cycle regulatory proteins, including downregulation of phosphorylated Rb and upregulation of the CDK inhibitor p27, which were likely responsible for the cell cycle delay/arrest as well as induction of the apoptotic cascade that manifested in the activation of caspase 7 and cleavage of PARP in the treated cells.

The findings demonstrate biological activity of these natural products when presented at ultra-diluted doses. Further in-depth studies with additional cell lines and animal models are warranted to explore the clinical applicability of these agents.
