Holy basil has a rich and fanciful history known since the Vedic age for its immense curative and multi-purpose utility. It has been the ‘Herb royale’ to the French, a sign of love by Italians, and a sacred herb in India. In the first century A.D. Roman naturalist Pliny reported that basil relieves flatulence, which had been subsequently proven true. In the Far East, the herb had been used as a cough medicine, and in Africa, it has been used to expel worms. American colonists considered holy basil is the essential ingredients in a snuff used to ease headaches. The plant grows all over India up to 2000 meters height. It is grown in houses, temples and gardens. An erect annual grows 0.5-1.5 meters in height and has red or purple quadrangular branches. The leaves are opposite, about 2-4 cm long, margins entire or toothed, hairy on both the surfaces, dotted with minute glands and are aromatic. The flowers are tiny, purple and inflorescence is a long spike or 12-14 cm in length. The fruits are small, smooth nut lets, reddish grey in color.

Tulsi has been used for thousands of years in Ayurveda, a Hindu form of medical science, for its diverse healing properties. It is mentioned in the Charaka Samhita, an ancient Ayurvedic text. Tulsi is considered to be an adaptogen, balancing different processes in the body, and helpful for adapting to stress. Marked by its strong aroma and astringent taste, it is regarded in Ayurveda as a kind of "elixir of life" and believed to promote longevity. If sprinkled over cooked food in stored water, tulsi leaves prevent bacterial growth during the eclipses.
Importance in Hinduism [3,4]
Every part of the Tulsi plant is revered and considered sacred. Even the soil around the plant is holy. The Padma Purana declares a person who is cremated with Tulsi twigs in his funeral pyre gains moksha and a place in Vishnu's abode Vaikuntha. If a Tulsi stick is used to burn a lamp for Vishnu, it is like offering the gods lakhs of lamps. If one makes a paste of Tulsi leaves and smears it over his body and worships Vishnu, it is worth several ordinary pujas and lakhs of Godan (donation of cows). Water mixed with the Tulsi leaves is given to the dying to raise their departing souls to heaven.
Just as Tulsi respect is rewarding, her contempt attracts the wrath of Vishnu. Precautions are taken to avoid this. It is taboo to urinate, excrete or throw waste water near the plant. Uprooting and cutting branches of the plant is prohibited. When the plant withers, the dry plant is immersed in a water body with due religious rites as is the custom for broken divine images, which are unworthy for worship. Though Tulsi leaves are necessary for Hindu worship, there are strict rules for it. Only a male must cut them and only in the daylight. A prayer of forgiveness may also be offered to Tulsi before the act.
Tulsi as a Diety [3,4]
The presence of tulsi plant symbolizes the religious bent of a Hindu family. A Hindu household is considered incomplete if it doesn't have a tulsi plant in the courtyard. Many families have the tulsi planted in a specially built structure, which has images of deities installed on all four sides, and an alcove for a small earthen oil lamp. Some households can even have up to a dozen tulsi plants on the verandah or in the garden forming a "tulsi-van" or "tulsivrindavan" - a miniature basil forest.
