When it comes to survival situations, it’s important to know which cacti are safe to consume and which ones can be harmful. While some cacti can provide a potential source of water in desperate times, there are a few species that you should avoid drinking from.
One cactus that you should definitely not drink from is the peyote cactus (Lophophora williamsii). This small, button-like cactus contains the hallucinogenic compound mescaline, which can have serious mind-altering effects. Ingesting peyote can lead to intense hallucinations and is illegal in many countries.
Another cactus to avoid consuming is the San Pedro cactus (Echinopsis pachanoi), also known for its psychoactive properties. Similar to peyote, San Pedro contains mescaline and should not be consumed unless under the guidance of a knowledgeable practitioner.
In addition to these psychoactive cacti, there are also cacti that are simply toxic and can cause harm or illness if ingested. For example, the Saguaro cactus (Carnegiea gigantea) has a bitter taste and contains toxic compounds that can lead to vomiting, diarrhea, and even paralysis. It’s best to avoid consuming the flesh of the Saguaro cactus in any situation.
Similarly, the Cardón cactus (Pachycereus pringlei) should not be consumed either. This tall and columnar cactus also contains toxic compounds that can cause gastrointestinal distress and other adverse effects.
It’s important to note that even among safe-to-consume cacti, proper preparation is necessary to avoid potential stomach upset or discomfort. The prickly pear cactus (Opuntia species), for instance, is generally safe to eat, but its spines and glochids (small hair-like structures) must be carefully removed before consuming the flesh. Additionally, the fishhook barrel cactus (Ferocactus wislizeni) is known to have edible pulp, but caution should still be exercised when handling and consuming it.
In any survival situation, it’s crucial to prioritize water sources that are known to be safe, such as natural springs or properly purified water. Relying solely on cacti for hydration should be a last resort, and even then, it’s important to have knowledge of which cacti are safe to consume and how to properly prepare them.
Remember, when it comes to consuming cacti in a survival situation, it’s always better to err on the side of caution and only consume those species that are known to be safe and non-toxic.
