Anita Kumari and Ashwani Kumar
Calotropis procera (Asclepiadaceae) is a wild shrub, which grows upto a height of 1-3 m and its leaves are 10-13 cm wide by 17-19 cm long. Calotropis procera commonly known as Akra is a popular medicinal plant. This plant is very drought resistant and grows throughout the Sahelian countries, notably in Burkina Faso.
Medicinal properties:
Scientific Name Apium graveolens Linn.
Family Apiaceae (Umbelliferae)
Used Part Fruits.
Distribution Area An erect, annual or biennial herb, wild in the foot-hills of north-western Himalayas and the outlying hills of Punjab, Himachal Pradesh and Uttar Pradesh.
Some of these plants of family Fabaceae are as follows :-
1. Acacia catechu Willd. ‘Khair’ (Mimoeaceae) :- The bark decoction is taken in the morning and evening for 3 days in stomachache .
2. Bauhinia vahlli W. and A. ‘Mahul’ (Caesalpiniaceae) :- Root decoction is taken 3 times a day for 4 days in fever.
3. Bauhinia variegata Linn. ‘Kachnar’ (Caesalpiniaceae) :- The bark decoction is administered orally for 15 days twice a day in tubercular glands. The flower powder is used 3 times a day for 10 days in haemorrhage.
4. Butea monosperma O.Kuntze. ‘Palas , Tesu’ (Paplionaceae):- Flowers and seeds are mixed in a decoction and used 2 times a day as wormicide. The bark decoction is used once a day for 1 month as tonic in piles.
Many plant names appear in similes and metaphors in Hindi literature e.g. the red lips of the beloved have been compared with red flowers of kachnar (Bauhinia variegata Linn.) and of the silk cotton tree.
In a Magahi song there is a mention of sandalwood (Santalum album Linn.) tree crying when the king takes Vanaprastha and becomes a Yogi. Aryani, 1965 stated that how beautiful is such personification of the qualities of plants and their parts in the human beings?
Folk proverbs : Things which cannot be remembered or explained easily are learnt, taught and emphasised through proverbs. A person who understands the tricks of the cunnings tell him that Tum dar dar Hum pat pat i.e. I will keep away from you.
