  • Human saliva displaying ferning. During the fertile phase of a woman's menstrual cycle an oestrogen surge causes salt crystals to appear in the saliva. When viewed under the microscope the crystalline salt structure resembles fern leaves and can be used as an indication of a woman's increased chances of conceiving at this time.

  • Illicium anisatum L. Illiciaceae Japanese Star Anise. Distribution Japan. This was also called Illicium religiosum and the fruits are toxic. Effects of taking Illicium anisatum tea include epilepsy, vomiting, shakiness and rapid eye movements (US Food and Drug Administration report, 2003). Lindley (1838) and Bentley (1861) thought that I. anisatum was used in cooking, but they were describing the uses of I. verum which is used as a spice in Asia. Illicium anisatum syn. religiosum is 'used to make incense in Japanese and Chinese temples and was called Skimi by Kaempfer. This derives from the Japanese word 'shi-kimi'. The seed pods of both species contain shikimic acid (the name being derived from the Japanese) from which Tamiflu, the antiviral drug was synthesised. Photographed in the Medicinal Garden of the Royal College of Physicians, London.

  • Buff-tailed bumblebee (Bombus terrestris) sitting on a purple flower. Bees are important pollinators and play a crucial role in promoting the growth of crops and flowers. The aposematic yellow and black banding pattern on the bee acts as a warning to deter predators.

  • Glaucium flavum Crantz Papaveraceae Yellow horned poppy. Distribution: North Africa, Western Asia to Europe. Contains glaucine which is toxic but in small doses may be bronchodilator. As Papaver corniculatum luteum it was known to Parkinson (1640) who reports it as bitter, so advises taking it in honey, as a purgative and analgesic
  • Human mustache hair
  • Human stem cell embedded in a 3D matrix, Cryo SEM

  • Helianthus annuus Greene Asteraceae. Sunflower, Marigold of Peru, Floure of the Sun. Distribution: Peru and Mexico. It was much recommended by Gerard (1633) who advises that the buds, covered in flour, boiled, and eaten with 'butter, vinegar and pepper, far surpass artichokes in procuring bodily lust’. Sadly, today only the seeds of sunflower are consumed, as the source of sunflower seed oil used in cooking. It contains mono and polyunsaturated fats, linoleic acid and oleic acid, and is low in saturated fats. As such it was thought to lower cholesterol and so the risk of heart disease, but it may increase the risk of breast and prostatic cancer. However a recent report BMJ2013
