Do not eat or drink anything during this period except purified water.  If you feel sick, immediately induce vomiting and drink plenty of water.  If activated charcoal is available, take that with the water.  Discontinue testing if you experience any adverse reaction. It is critical that you use exactly the same part of exactly the same kind of plant, and that you prepare it in exactly the same way as you did the initial sample. Abstain from any other food except purified water.  Induce vomiting immediately as above if you should feel ill.  If no reaction has occurred, you may assume  only that particular part of the plant is safe to eat, and only as prepared during the test. If the first plant part you choose appears contact-poisonous, you may immediately test a new plant on your other arm or behind your knee.  If the plant causes a reaction before you have swallowed it, wait until the symptoms have disappeared before testing a new plant.  If you have an adverse reaction after you've swallowed the plant, wait until symptoms have disappeared and start a new test.  Although there may be edible parts of the plant you initially chose, it is preferable to move on to a different plant for subsequent tests. If you are in a situation where you have access to other sources of safe food, you can incorporate this test into your diet more gradually by splitting it up into 3 stages, and using your 8 hours of normal sleep as the 8 hours of the pre-test for each stage. Again, this should only be used if you are in a survival situation (e.g. your existing food rations are running low, and you need to start testing another source before your current one is depleted) or if you cannot find documentation for a particular plant and are willing to undergo the risks (poisoning and death) involved.   Wake up and do the contact-poisonous part of the test. After 8 hours, eat a normal meal (not of the plant under test). Next morning, complete the test up to swallowing a single piece. After 8 hours, assuming you are still alive and well, eat a normal meal again. Eat the full sample of the plant under test on the 3rd morning. After 8 hours, celebrate life and the adding of a new edible plant to your experience by eating a nice meal. Don't disregard any other steps, or tips, or warnings; this alternative method is only to save your body from the stress of 24 hours of fasting. This method also enables you to continually test new plants in your area without going hungry for more than 16 hours a day, and only 8 hours on the final day, assuming 1/4 cup of the food can sustain you.
