Tulsi is one of the most religious plants in India, especially for Hindus, and is also famous for its herbal uses and its positive Vastu points. Popularly known as Holy Basil, Tulsi is extremely sacred to the Hindu culture and Ayurveda.
It is said that Tulsi, as a plant, is the manifestation of Maa Lakshmi, and a home where the Tulsi plant remains healthy, is a home where prosperity and luck never leave the gate. It protects the people from negative energies, doom, and even ailments with its leaves.
The respect for Tulsi is such that there is also a day dedicated to Tulsi Vivah, where she is married to Shaligram, a form of Lord Vishnu.
