Amalaki: A Wonder Fruit
Ayurveda takes care of the patient as a whole with its holistic approach. Various Ayurvedic herbal and herbomineral preparations are used for the treatment of chronic and degenerative diseases without any side-effect.
Amla (Aonla) is one of the oldest Indian fruits. It is known as Amalaki in Sanskrit. It is a rich source of ascorbic acid (vitamin C). Vitamin C found in amla fruits is heat stable, because it is bound to tannins which allow it to be cooked in preparations like chyawanprash a rejuvenating herbal preparation. The fruits of amla have been used in Ayurveda as potent Rasayana. Perhaps there is no medicinal plant in nature with such a vast range of medical benefits. It is used as an anti-oxidizing, anti-bacterial and anti-inflammatory agent. Anti-oxidizing property resides in tannoids. It is one of the three constituents of the famous Ayurvedic preparation, Triphala, which is prescribed in many digestive disorders. The medicinal properties of amla have been elaborately described in ancient Ayurvedic texts, such Charak Samhita and Sushrut Samhita. It is used in making pickles and preserves. Preservation of amla is one of the speciality of the Indian fruit-preservation industry. It is said to be the native of tropical South-Eastern Asia, particularly central and southern India.

Habitat
In Himachal Pradesh, the amla seedlings grow wild in the forests up to elevations of 1,500 m. It is found in dry deciduous forests of India and Burma, and in the extreme north-west, ascending to 1,450 m. It is also found in China and Sri lanka. The major difference between these wild trees and the large-fruited types cultivated in the plains is of winter-hardiness; whereas the improved types are highly susceptible to frost injury, the wild amla are not damaged at all. Amla is a heavy bearer and the fruits also remain free from the attack of birds and wild animals. This plant also remains free from any serious disease and major insect pest.
Botanical Characters
The Indian gooseberry tree is a small, deciduous tree of small to medium size up to 5.5 m height that has feathery branches. Its bark is usually light brown to black, coming off in thin strips or flakes, exposing the fresh surface of a different colour underneath the older bark; the average girth of the main stem is 70 cm; in most cases the main trunk is divided into 2 to 7 scaffolds very near the base. The berries are fleshy and pale green, and have 6 dimly marked lobes. The flowers appear in dense clusters under the leaves, and hence the fruits grow in the same manner. The tree is indigenous to India. Fruits, fleshy, almost depressed to globose, 2.24 cm in diameter, 5.68 g in weight, 4.92 ml in volume, primrose yellow base.
The stone of the fruit is six ribbed, splitting into three segments, each containing usually two seeds: seeds 4–5 mm long, 2–3 mm wide, each weighing 572 mg, 590 microliters in volume.
The Flowering and Fruiting Season
The flowering season was observed to occur from the middle of April to the first week of May under Sanwara (H.P.) conditions. The flowering reached its peak in the end of April.
The fruiting season of amla is exceptionally long. The fruit in this area become fit for harvesting in December. They can be retained on the tree up to March without any significant loss in quality or yield. The picking of fruits is generally done by the villagers in February and march. In Western India fruiting season is October to December. The average yield of wild amla-trees growing in the forests is 23.5 kg. per tree.
Amla Fruits
Chemical Constituents
A number of laboratory tests conducted on the Indian gooseberry show that for every 100 grams of the berry, it yields between 470 and 680 mg of vitamin C, which increases in case, the juice is extracted. The fruits contains 20 and 15 times more vitamin C than grapefruits and lemon, respectively. Dehydrated berries yield 2.42 to 3.47 g of vitamin C for every 100 g. The fruit, (as well as its bark and leaves) contains a significant amount of tannins too. The seed of the berry contains a fixed oil, essential oil, and phosphatides.
The fruit pulp, which constitutes 90.97 % of the whole fruit, contains 70.5 % moisture. The total soluble solids constitute 23.8 % of the juice. The acidity of aonla is 3.28 % on pulp basis. The pulp contains 5.09 % total sugars and 5.08 % reducing sugars. The ascorbic acid content is 1,094.53 mg per 100 ml of juice. The tannins and pectin content of the pulp is 2.73 % and 0.59 %, respectively. The fruit pulp contains 0.75 % protein. The mineral content of the edible portion, as represented by its ash, is 2.922 %. The percentage content of the mineral elements, viz; phosphorus, potassium, calcium, magnesium, and iron is 0.027, 0.368, 0.059, 0.248 and 0.004, respectively.
