This is the classical Rehmannia Six Combination used for centuries in Asia. What distinguishes Dragon Herbs Rehmannia Six Combination from other brands is the quality of the herbs used to produce it and the production technology.

ALL HERBS in China (and from most places) come in different grades based upon their variety, seed stock, growing source, growing conditions, care of the cultivators or collectors, and processing at various stages of the supply chain and during production.

That’s a lot to consider. But Dragon Herbs does take ALL these factors into account in selecting our raw materials and in producing our herbal products.

Rehmannia Six Combination is so widely consumed in China that many domestic herb factories produce it. Most of this production uses low grade herbs for price reasons. Many of the peasants of China take Rehmannia Six Combination, so many factories produce it with very cheap materials so that it costs just pennies.

Dragon Herbs does not use low grade, less effective, raw materials for Rehmannia Six Combination or any of its products. Dragon Herbs identifies sources of the BEST raw material, the kind preferred in Shanghai or Hong Kong by those who know herbs and want the best. We use this premium material to produce this important formula.

Production technology also matters. Most factories just throw the herbs into a tank and cook the whole thing for a couple of hours, then they make a powdered extract of the tea using a lot of excipient (usually not natural). Dragon Herbs uses low temperature extraction using very pure water and no chemicals. We add the herbs carefully at incremental stages. Some of the herbs in Rehmannia Six Combination can only be cooked for a few minutes. These “short cook” herbs are cooked separately and carefully and added at the end. For example, the Moutan in Rehmannia Six Combination must be cooked just for a few minutes at most because of its aromatic oil content.

One very important process that most factories skip involves the collection of aromatic oils from the tea. Real Rehmannia Six Combination has a sweet-spicy aroma. This is from the aromatic oils in the herbs. If the herbs are overcooked and the oils are allowed to evaporate, the true power of Rehmannia Six Combination cannot be achieved – even if good quality herbs are used.

Dragon Herbs always processes its herbs using an “oil trap.” An oil trap is a sophisticated device connected to the extraction system. It captures evaporating aromatic oils and collects them in crystallized form. These collected 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!

When you smell Dragon Herbs Rehmannia Six Combination, and other Dragon Herbs powdered extracts, you can always smell the aromatic oils. These oils are not present in most other brands of powdered extract. It is something we pay extra for, but you the customer don’t. We know that for an herbal extract to work, it must be made correctly and with the best technology available in the world.*
