What is the name of the so-called 'mexican good-luck plant'?

Question

My mother says that there is a plant (more like a bush) that hispanics will grown next to the doors of the house. It is supposed to help ward off evil spirits too.. long leaves with small bunches of flowers. I believe she said it was similar in looks to the mexican fire bush. If anyone might know, will you send me a link to pictures of it??? THANKS!!

Answer 1

It's Aloe vera or sabila in Spanish.

I translated text from the link below using Babel Fish, so forgive the translation:

It is recommended to always have a plant in the social place of the house. In South America, Mexico and Central America, are very extended its use in this sense, placing it next to the access road to the house, or next to the front door, to detect and to absorb the strange or negative energy of the places that live. Usually one puts to the plant a red bow when love is invoked and a green bow when the luck is invoked. They hang also it by the root behind the door to the entrance of the houses to protect them. Its use in chamánicos (Shamanic) rituals by its great power power is very frequent. It is compared with the power of the diamond in the mineral world. In mystical sense, the power is attributed to him to purify the soul.
