  • ATPase (adenosine triphosphatase) is a class of enzymes that aid the breakdown of ATP (Adenosine triphosphate) into ADP (Adenosine diphosphate) with a release of energy.

  • Silphium perfoliatum L. Asteraceae Indian Cup. Distribution: North America. Austin (2004) records that another species, S. compositum, was used by Native Americans to produce a chewing gum from the dried sap of the roots, and Native American medicinal uses for 'Indian Cup' are probably referrable to S. compositum and not S. perfoliatum. Silphium perfoliatum contains enzymes that inhibit trypsin and chymotrypsin which gives it resistance to fungal, bacterial and insect attacks. Male gall wasps (Antisotrophus rufus) alter the chemistry of the plant to enable them to locate females, making it a 'signpost' plant. The gall wasp lays its eggs in the stem of Silphium laciniatum, to provide food for the larva on emergence, and the galls containing a male or a female wasp will cause the plant to give off a different chemical odour. Emerging male wasps can search for female wasps, which emerge later, by locating this chemical fragrance which acts as a sex pheromone proxy (Tooker et al Proc Natl Acad Sci U S A. 2002 Nov 26
  • Iris unguicularis Poir. Iridaceae. Algerian iris. Rhizomatous perennial. Distribution: NW Africa, E. Mediterranean It has scientifically-based potential. The rhizomes contain the chemical kaempferol which inhibits the enzyme alpha-glucosidase in the gut, reducing the rate of glucose absorption. This could be used to prevent the dangerous peaks of blood sugar that occur in diabetics and reduce eye and kidney complications. The unprocessed rhizome contains iridin, a toxic glycoside, which causes 'nausea, vomiting, diarrhoea and skin irritation'. Photographed in the Medicinal Garden of the Royal College of Physicians, London.
  • Vicia faba L. Fabaceae. Broad beans, Fava bean. Distribution: N. Africa, SW Asia. Culpeper (1650) writes: 'Fabarum. Of Beans. Of Bean Cods (or Pods as we in Sussex call them) being burned, the ashes are a sovereign remedy for aches in the joints, old bruises, gout and sciaticaes.’ The beans are perfectly edible for the majority, but 1% of Caucasians, predominantly among Greeks, Italians and people from the Eastern Mediterranean regions, have a genetic trait in that they lack the ability to produce the enzyme glucose-6-phosphate dehydrogenase. As a consequence, eating broad beans or even inhaling the pollen, causes a severe haemolytic anaemia a few days later. This condition is known as favism. The whole plant, including the beans, contains levodopa, a precursor of dopamine, and some patients with Parkinsonism report symptomatic improvement after commencing on a diet that contains these beans regularly. A case of neuroleptic malignant-like syndrome (fever, rigidity, autonomic instability, altered consciousness, elevated creatine phosphokinase levels) consequent on abrupt discontinuation of a diet containing plenty of broad beans, has been described in a patient with Parkinsonism. This is usually seen when patients abruptly discontinue L-dopa therapy. Photographed in the Medicinal Garden of the Royal College of Physicians, London.
