The most poisonous spider in the world
According to the Guinness Book of Laws, among the current spider species, the Brazilian wandering spider living in South and Central America is the most poisonous spider in the world. Wandering spiders are also known as banana spiders, supposedly because they like to hide in bananas. Usually female spiders are slightly larger than males, with the largest female spiders being 3-5 cm and males 3–4 cm. The whole body is gray with some small brown dots on it. Parts of the body are dark red. Compared to other spiders, the Brazilian wandering spider is a large spindle-shaped spider that can easily become a one-word horse with a maximum length of up to 15 centimeters. And their legs are very thick, covered with spikes, and they are also majestic when they walk.

With the persecution of the natural ecological environment, more and more Brazilian wandering spiders hide in bananas and drift to the city. Their wandering foraging methods make urban people very dangerous. Because this spider has a big feature is that it is aggressive. When there are people around it, even if the person is not aggressive, it will take the initiative to bite you in order to protect itself.
After being bitten by them, the wound will often cause infection because it is difficult to heal, and even if it is serious, it will cause life-threatening. According to local news reports in Brazil, many people who are attacked by wandering spiders are taken to the hospital or killed every year.
Spider venom makes people have a "physiological response"?
According to the bitten patient, after being bitten by a wandering spider, there will first be intense local pain and swelling, followed by an irregular heartbeat, and even apnea, pulmonary edema and vomiting. If the bite is not treated with serum in time at the moment of the bite, the wound may lead to death. What makes the venom of a wandering spider so lethal? Scientists have made in-depth research and analysis of such a situation and finally found the answer. It turned out to be a neurotoxin called PhTx3 (Phoneutria nigriventer toxin-3).
Some spiders secrete toxins that can be used to treat them
This toxin can hinder the release of glutamate and the absorption of glutamate and calcium by synapses, causing muscle loss of control and breathing disorders, ultimately leading to paralysis and suffocation. The excitement of the sensory nerve receptor serotonin 4 (serotonin 5-HT4) causes severe pain and inflammation. In addition to these physiologically inappropriate pains, men have said that they will have abnormal physiological reactions for a long time. Time can last for several hours, eventually leaving an irreversible effect that creates sexual impotence.

Through the study of PhTx3, the scientists successfully decomposed the compound of "PnTx2-6" from the venom of the Brazilian wandering spider. This compound, also known as "Viagra in Nature", can help people in need a lot. To ensure the compound's functionality, the scientists experimented with the drug on mice. It has proven to function better than other common drugs for mice and has a wider range of applications.

This is undoubtedly great news for many patients. "Natural Viagra" offers a great solution for those who cannot be treated with traditional therapies.
brief summary
Like a coin, everything has two sides. Although the Brazilian wandering spider is highly poisonous and can cause people to die, scientists have also found a way to help some male patients through research. Although we do not know what the side effects of this substance are, we believe that with the joint efforts of scientists, we can better help everyone.
