There are thousands of species of plants and trees which may cause skin irritation as a result of contact with them, or temporary blindness from rubbing your eyes after contact with the plant. Some of these plants may be growing very near to you right now. Most species of Spurge (Euphorbias) are toxic and contact with their milky sap is dangerous. Interestingly, the Pointsettia is a popular plant sold around Christmas time but this plant is also a Euphorbia and can be hazardous if handled carelessly. All plants with a milky sap should be regarded as dangerous. Some plants may have edible parts while other parts of the plant are dangerous - a good example is the Cashew Nut tree which is dangerous to touch but the nuts are delicious. People who work closely with plants should take precautions such as wearing long-sleeved gloves and safety goggles to avoid skin and eye contact. Any keen gardener should take the time to identify all the plant species in their garden (including common weeds) and research them for possible hazards. Any plant sap that gets onto your skin should be washed off with soap and water immediately - do not use alcohol wipes which may actually cause the sap to penetrate the skin surface more easliy - and any skin that has come into contact with plant sap should also be shielded from sunlight because in some cases the sap becomes irritating when exposed to ultra-violet light.
Interestingly, the sap of some plant species may be used to alleviate the irritation caused by toxic species. Common Sorrel (Dock leaves) is well known for this property and also Impatiens (Busy Lizzie).
