Chyawanprash is a delicious nutritive jam that has been used in Ayurveda for thousands of years, offering a wide range of health benefits. In Sanskrit, the word, “prash” refers to a specially prepared food. It is said that two ancient sages of Ayurveda concocted this particular formula to restore youth to the elderly sage, Chyawan—thus the name, “chyawanprash”.The transliteration from Sanskrit to English has resulted in a variety of spelling variations, including: chyavanprash, chyavanaprasam, and chyavanaprjasha. 
Ayurvedic jams are often used as anupans (carriers) for other herbs, but they can also be used on their own and frequently are—especially as rejuvenatives and aphrodisiacs.The Ayurvedic jam known as chyawanprash is made with a base of amalaki fruits (Emblica officinalis) and typically contains a number of other herbs, ghee, sesame oil, sugar, and/or honey. The honey, ghee, and sesame oil serve as yogavahis (catalytic agents) to carry the herbs deep into the tissues, while the sugar is considered a samvahaka dravya (preservative substance) which helps to safeguard the clinical efficacy of the main ingredient, in this case amalaki.
Amalaki, also known as amla, is renowned for its rich antioxidant content and is generally known to contain vitamin C. Some even say that amalaki has one of the highest known concentrations of vitamin C in the plant kingdom.More importantly, the vitamin C frequently contained in the amalaki fruit is stabilized by the presence of tannins, which help to preserve the vitamin content, even through processing.2 This is particularly relevant in a preparation such as chyawanprash, which requires extensive cooking.

How to Use Chyawanprash:
Because taste plays such an important role in the digestive process and signals the body to initiate its own supportive mechanisms, Ayurveda traditionally recommends tasting herbs. As a delicious jam, chyawanprash offers those who use it the full experience of taste, further enhancing its efficacy.
When To Take Chyawanprash:
As a rasayana, chyawanprash is typically taken in the morning, or sometimes in both the morning and the evening. Chyawanprash can be taken on a long-term basis as part of a program designed to support overall strength and immunity, even supporting the natural systems of the body after a bout of stress or illness.
For others, it is more appropriately used seasonally, as a tonic in the winter months.
Side Effects:
While there is little information on side effects associated with chyawanprash, no toxic effects of amalaki (its main ingredient) have been observed in scientific studies.
Contraindications:
Avoid chyawanprash if there are known allergies to Emblica officinalis, other members of the Phyllanthus family, or to any other ingredients in chyawanprash.
For pitta-types or those with pitta imbalances, chyawanprash may be heating during hot weather.It is likewise contraindicated in cases of indigestion or diarrhea.
Use caution in patients with hypoglycemia and in those taking anticoagulant or antiplatelet medications.
