“Blocks cancer cell growth”.






Quercetin is documented as being safe with a low toxicity and has been used to treat asthma, hay fever and eczema.  What alerted me to the product was its use in gout, arthritis, and pancreatitis as it is an excellent anti inflammatory - plus a trial in the USA which showed that it blocks the androgen (hormone) activity in human prostate cells.  Now these prostate cancer trials are in a laboratory on prostate cancer cells in dishes, not yet on humans. However, it is significant because it could be a method of stopping the growth of cancer cells without using the hormonal drugs currently used, such as Zoladex and Casodex.


The trials led to newspaper articles which advised “an apple a day may help stop the growth of prostate cancer. A compound found in the apple called, (surprise, surprise), Quercetin blocks the hormone that the cancer cells need to grow.  This blockage can prevent or stop the growth of prostate cancer say researchers”. 


It is early days yet but these trials have a great significance for men at the end of their hormone treatment because the cancer no longer responds to the lack of testosterone and begins to grow again.  The Doctor conducting the trial said he feels this natural product may inhibit the prostate cancer receptors and keep the cells under control.


“Dr Patrick Quillan of Cancer Treatment Centres of America has assembled some interesting data on Quercetin in cancer.


Quercetin ‘may be one of the most potent anti-carcinogens in nature’.

Quercetin has ‘the potential to revert a cancerous cell back to a normal healthy cell’.


Quercetin also “induces apoptosis or programmed cell death in otherwise ‘immortal’ cancer cells”. 

It..  “inhibits inflammation by reducing histamine release and reduces tumour cell-proliferation”.


Dr. Quillan also refers to new studies that show that:-



Among the reasons for this may be the fact that Quercetin:-


‘competes with oestrogen for binding sites, thus defusing the damaging effects of oestrogen’ in breast cancer”.


(Don’t forget that both breast and prostate cancers are hormone cancers, and there is a body of opinion that feels that it is oestrogen and not testosterone that is responsible for prostate cancer Ed.).


Quercetin is also ‘a potent antioxidant.’ It ‘inhibits capillary fragility which protects connective tissue against breakdown by tumours, in angiogenesis and metastasis.


Quercetin also interferes with metastasis by reducing cell aggregation or ‘stickiness’. It ‘helps to eliminate toxic metals through chelation’.”

Quercetin can help in the fight against cancer. It was a result of this that the PHA (Prostate Help Association) approached a UK Pharmaceutical Company to produce Quercetin Capsules for us. 


These capsules and tablets have over the years been produced exclusively for the 
Prostate Help Association by

Lifeplan Products Ltd. an ISO 9000 company.

Lifeplan are accredited by the MHRA

(Medicines and Healthcare Products Regulatory Agency ),

so all their products are produced to medical standards.

Each step of the manufacture from selection of the product to its final encapsulation is monitored and checked for purity and quality.


Each tub contains 90 capsules. The recommended dose is one capsule three times per day, one hour before or after meals.
