Dr Oakeley is the garden fellow at the Medicinal Garden of the Royal College of Physicians. This tiny oasis of living medical history contains 1,300 plants, that have been used (at some time or on some continent) as medicines or as the source of medicines, or are named to commemorate physicians.

The cards come in packs of 10, and contain the message 'Seasons Greetings'.
