Jalapeno History/Mythology

Jalapeños are medium sized chili peppers that are used in many Spanish dishes worldwide. These peppers are between 2-3 inches in length, and they are spicy by nature because of capsicum.

According to Colorado State research,

“Capsicum is derived from the Greek word, kapos, “to bite”. The heat comes from a group of alkaloid chemicals called capsaicinoids, principally capsaicin and dihydrocapsaicin. These oily compounds are very soluble in fat and alcohol, but insoluble in water.” [5]

When looking back into the history books of how jalapeños were discovered, they have quite a remarkable story. These peppers date as far back as the Aztecs, and they were a staple for the people to smoke with because their skin was so thick. To this day, it is the most commonly grown chili pepper in Mexico, and for good reason! [6]

According to SB Nature,

“These “peppers” originated in the New World. Since ancient times, chilies have been essential elements of both food and medicine among indigenous peoples from the American Southwest to South America. Although they first evolved south of Amazonia, chili seeds have been found in cultural deposits more than 9000 years old in the Tehuacan Valley, Mexico.” [7]

Both the Aztec and Mayan people ate chili peppers with nearly everything, and they even used them to smoke as mentioned above. To the people, these peppers were said to cure colds, depression, and give the body overall strength, which made them very popular. For the people who fasted for religious purposes, the fast wasn’t from food and water, but just from eating jalapeño peppers and salt. This goes to show just how much they consumed them, if they used them as the staple “fasting” food ban for all people of the religion. They had other uses as well, for some children they would be punished and fumigated with chili smoke, and around other tribes it was seen to prevent witchcraft. If you did not eat the peppers, you were automatically ruled as a sorcerer.

Now you can readily find jalapeños in every grocery store, garden bed, and Mexican restaurant in the Southwest part of the country, as well as Mexico. Before, they were grown just in Mexico, so getting your hands on one required traveling, but they quickly spread all around the world.

According to SB Nature,

“Columbus actually undertook his voyage with the goal of finding a shortcut to the “Spice Islands” of Indonesia, source of spices like nutmeg, mace, and cloves that had been prized throughout Europe for centuries. They helped to mask ‘off’ flavors of food in a time before refrigeration and were also a status symbol: highly spiced foods were a prerogative of the very rich because exotic spices were so expensive and hard to obtain. It was the Portuguese who introduced chilies through their trading activities to Africa, India, and much of Asia.” [7]

Jalapeño Health Benefits

When it comes to the jalapeño and health benefits, I have just one word: capsaicin. Aside from this word just being really cool to say out loud, it also is very healthy and beneficial to your overall wellbeing. It has been said to be linked to natural pain relief, and Healthy Eating San Fran quotes, “There’s also some very early research suggesting capsaicin might have some cancer-fighting properties, but scientists still aren’t sure how effective it is.” [9]

Being around that family atmosphere when cooking Mexican food or dining out at a restaurant that serves many different jalapeño dishes is enough of a health benefit in and of itself!

Other important and notable benefits to consuming the jalapeno pepper are weight loss benefits due to the presence of capsaicin, as well as relief from arthritis pain. Nasal congestion relief, prevention of cancer, and headache relief are also some exciting benefits that occur when you eat anything jalapeno related! Growing jalapenos on a jalapeno tree is a very cost effective way to make sure you get your fix! Just make sure you plant your tree in a place where there is a lot of sun. You cannot forget that simple detail in the location. [10]

Jalapeño Varieties

When it comes to different jalapenos to choose from, there is quite the variety! The most popular varieties are:


“Standard jalapeno varieties produce green peppers, about 3 to 4 inches long, with a heat factor of around 5000 Scoville units.


Early jalapeño plants offer 3.5-inch peppers that are hotter than the standard jalapeño, with an average Scoville rating between 7000 and 9000.


Those who like the chili flavor but find the heat of standard jalapeños unpleasant may want to try one of the several mild varieties of jalapeños. “Fooled You” and the “Senorita Jalapeno” are mild jalapeño varieties, with a Scoville rating of just 400 units.


Heirloom jalapeño varieties offer unusual fruit characteristics from the standard chilies. For example, the “Sweet Jalapeño” variety produces a smaller, 2-inch pepper with a mild level of heat and sweet, rather than pungent, flavor.” [11]
