Man suffered psychotic episode after drinking four cups of St John's wort-laced herbal tea a day

A man lost touch with reality during a psychotic episode after drinking four cups of herbal tea a day, it has been reported.

The Italian was hospitalised after suffering speech problems, delusions and paranoid thoughts – such as believing people could read his mind. Friends sought help for the unnamed 25-year-old who they say had been 'acting strangely' for a few days and behaving as if he were 'under the influence of an illegal drug'. 

For months previously, he had been drinking herbal tea laced with St John's wort – a popular over the counter remedy used to treat depression, seasonal affective disorder (SAD), sleep problems, mild anxiety and jet lag.

The doctors who treated the man at AUSL Modena hospital in Italy say they could not rule out that the herb, known botanically as hypericum perforatum, did not contribute to the man's psychosis.

A compound in cannabis is 'significantly' effective in destroying cancerous tumours in leukaemia

A compound in cannabis is 'significantly' effective in destroying cancerous tumours in leukaemia, research suggests.

A new study found that combining existing chemotherapy treatments with cannabinoids – the active chemicals in cannabis – had better results than chemotherapy alone.   The findings suggest that a lower dose of chemotherapy can be used on patients, minimising side effects of the treatment, say researchers.

Furthermore, scientists discovered that order the treatment was administered was crucial - using cannabinoids after chemotherapy resulted in a greater death of the blood cancer cells.

Lead author of the study, Dr Wai Liu, from St George's, University of London, said: 'We have shown for the first time that the order in which cannabinoids and chemotherapy are used is crucial in determining the overall effectiveness of this treatment.'

Eating red onions may help to fight cancer

Eating red onions may help to fight cancer, new research suggests.

The tasty vegetable, commonly used in Mediterranean cuisine, is full of powerful compounds that help to kill tumours. One type known as anthocyanins, which are responsible for its dark colouring, are believed in inhibit the spread of the disease. While a flavonoid called quercetin has the same effects by shrinking the size of cancerous masses, experts say. But any type of onion, regardless of its colour, may help to destroy cancer, Canadian scientists claim.

Study author Abdulmonem Murayyan, of the University of Guelph, said: 'We found onions are excellent at killing cancer cells. Onions activate pathways that encourage cancer cells to undergo cell death.  They promote an unfavourable environment for cancer cells and they disrupt communication between cancer cells, which inhibits growth. It makes sense that the red onions, which are darkest in colour, would have the most cancer-fighting power.'
