<p>This is a well known herbal formula and is used as a tonic supplement.</p> <p>The Codonopsis and Astragalus combination is a well-known herbal formula and is used as a tonic supplement. This is the classic Ginseng and Astragalus combination that has been used in Asia for many centuries. What sets the Codonopsis and Astragalus Combination from Dragon Herbs apart from other brands is the quality of the herbs it is made from and the production technology that is used.</p> <p>All herbs in China (and most places) come in different grades based on their variety, seed stock, growing source, growing conditions, care of the cultivators or gatherers, and processing at various stages of supply and production. That's a lot to consider. But Dragon Herbs takes ALL factors into account when selecting our raw materials and producing our herbal products. Dragon Herbs does not use low quality and less effective raw materials for Codonopsis and Astragalus Combination or any of its other products. Dragon Herbs identifies sources of the best raw material, the kind that is recommended in Shanghai or Hong Kong by those who know herbs and want the best. We use this premium material to produce this important formula.</p> <p>Production technology is also important. Most factories just throw the herbs in a tank and boil the whole thing for a few hours, then they make a powdered extract of the tea with a lot of additives (usually not natural). Dragon Herbs uses low temperature extraction with very pure water and no chemicals. We carefully add the herbs in incremental stages. Some of the herbs in Codonopsis and Astragalus Combination can only be boiled for a few minutes. These "short cook" herbs are boiled separately and carefully and added at the end. For example, the Dang Gui should not be boiled as long as some of the other herbs because of its high aromatic oil content. Aged Mandarin Peel and Fresh Ginger should only be boiled for a few minutes at most because of their aromatic oil. This is a real secret (revealed) of superior herb production.</p> <p>A very important process that most factories skip is the collection of aromatic oils from the tea. True Codonopsis and Astragalus Combination has a sweet-spicy aroma. This comes from the aromatic oils in the herbs. If the herbs are overcooked and the oils are allowed to evaporate, the true power of Codonopsis and Astragalus Combination cannot be achieved - even if good herbs are used. Since we use beautiful herbs to make this formula, the result is sublime. Dragon Herbs always processes the herbs with an 'oil trap'. An oil trap is a sophisticated device that is connected to the extraction system. It takes the evaporating aromatic oils and collects them in crystallized form. These essential oils are therefore not lost. They are added back into the extract at the end of the process. And this makes all the difference!</p>
