Surviving in the wild often requires resourcefulness, especially when it comes to finding food. The Universal Edibility Test (UET) is a systematic method to determine whether a plant or part of a plant is safe to eat. While this test is a valuable tool, it should be approached with caution and patience. Here’s a step-by-step guide on how to use the Universal Edibility Test.
Preparation
Before starting the test, gather a small sample of the plant you wish to test. It's important to be thorough and methodical to avoid potentially dangerous plants. Here are the key preparatory steps:
1. Separate Plant Parts: Different parts of a plant can have varying levels of toxicity. Separate the roots, stems, leaves, buds, and flowers.
2. Inspect the Plant: Check for any signs of toxicity, such as a milky sap, fine hairs, thorns, or an almond-like scent, which can indicate the presence of cyanide.
The Testing Process
The Universal Edibility Test involves several stages, and each part of the plant should be tested separately. Here’s how to proceed:
1. Contact Test:
Rub a small piece of the plant on the inside of your wrist or elbow.
Wait for 15 minutes to check for any adverse reaction like redness, itching, or burning.
2. Lip Test:
If there’s no reaction from the contact test, place a small portion of the plant part on your lips for 3 minutes.
Check for any tingling, burning, or numbness.
3. Mouth Test:
If the lip test shows no reaction, place a small piece in your mouth and hold it without chewing for 15 minutes. Avoid swallowing.
Observe any unpleasant reactions such as burning, tingling, or numbness.
4. Chew Test:
If there are no adverse reactions from the mouth test, chew the piece for 15 minutes without swallowing.
If you feel any negative effects, spit it out immediately.
5. Swallow Test:
If the chewed plant part causes no problems, swallow it.
Wait for 8 hours and monitor for any signs of discomfort, nausea, vomiting, or other adverse effects. During this time, consume no other food.
6. Consume More:
If after 8 hours there are no adverse effects, eat a small quantity of the same plant part (around a quarter cup).
Wait another 8 hours and monitor your body’s reaction.
Important Considerations
Be Patient: The entire process can take up to 24 hours or more, so patience is essential.
Know the Limits: The UET is not foolproof and should be complemented by knowledge of local flora and potentially harmful plants.
Avoid Risky Plants: Certain plants are universally toxic, such as hemlock, oleander, and castor bean plants. Always avoid these.
Stay Hydrated: Ensuring you have a safe source of water is crucial during this process.
Conclusion
Using the Universal Edibility Test is a valuable skill for anyone venturing into the wild. It requires patience and careful observation to avoid the dangers of consuming toxic plants.
Always approach unknown plants with caution, and whenever possible, supplement your efforts with knowledge from field guides or advice from experienced foragers.
