Products

What is the shelf life of the Korean red ginseng products?
Cheong-Kwan-Jang’s Korean red ginseng root products are vacuum packed in tins. If the tins are left unopened, it is possible to store them for a period beyond 10 years, as the ginseng roots are boiled by steam and dried before being packed, allowing them to be preserved for a long time.
The shelf lives of Korean red ginseng processed products, such as the extract, pills, powders and drinks range between 2-3 years.
For online orders, only products with an expiry date that is at least 6 months away will be delivered, unless otherwise highlighted on the product page.
Why only 6-year-old Korean red ginseng roots are used in Cheong-Kwan-Jang’s product?
Ginseng reaches its peak in its sixth year of growth, at which there is a balanced development of the head, main body and lateral tail roots. In the sixth year, ginseng contains a balanced mix of the major medicinal properties and components, hence they are more highly regarded than 4 or 5-year-old ginsengs. However, due to the high vulnerability to blight and insects, deceleration of growth, woody disuse and expansion of inner cavities as the ginseng enters its 7th year of growth, 6-year-old ginseng are harvested as the ginseng is considered to be at its peak.
Are there any possible adverse effects from the consumption of Korean red ginseng?
Korean red ginseng is non-toxic and is considered a long-term, high functional herb in TCM. Cleansing reactions or abnormal symptoms may occur depending on individual body conditions and constitutions. However, these reactions are said to be part of a healing process which might take place for up to a week from consumption, and will gradually dissipate over time.
In the case of allergic reactions, symptoms are expected to disappear once consumption is stopped.
What is the relationship between Korean red ginseng and internal body heat?
Ginseng does not increase body temperature. However, Korean red ginseng helps to regulate the body and blood pressure, making us feel that the body temperature has increased, giving the wrong perception that Korean red ginseng is heaty in nature.
In general, it is advised that a person suffering from fever or cold should not consume Korean red ginseng.
Is there any difference between the grades of Korean red ginseng?
Korean red ginseng roots are classified into Heaven, Earth, Good and Cut grade according to the appearance and condition of the tissue. External factors include the shape, condition of outer skin, cracks and color. The internal condition of the tissue depends on the compactness of the root, the inner whiteness and the content of active substances.
Heaven grade roots have more compact and darker inner tissues compared to the Earth and Good grade roots. Usually, Korean red ginseng with compact tissue and good appearance has higher quality and better efficacy.
Heaven ginseng roots are certified to have the most outstanding qualities, and are very limited in quantity, hence are very expensive and valuable.
