A high percentage of the population could be endangering their health by taking herbal medicines without checking with a health professional first according to Peter Houghton, Professor in Pharmacognosy, King’s College London. Speaking today (6 September) at the BA Festival of Science, Prof Houghton warned of the risks of herbal remedies interacting with conventional medicines.
There is widespread belief that all herbs are safe because they are ‘natural’. However, some plant material may contain compounds which are toxic and the amount present can vary much more than with a synthetic product. And, unlike pharmaceutical drugs, there are no strict quality standards for herbal medications.
"Although your risk of dying from taking a herbal remedy is extremely small, some do interact with other medicines with serious consequences. For instance, St John’s Wort makes many prescription drugs used to treat conditions such as heart disease, depression, seizures, certain cancers or to prevent conditions such as transplant rejection or pregnancy (oral contraceptives) less effective," said Prof Houghton.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
