What is di huang (Rehmannia glutinosa)?

Rehmannia glutinosa is a perennial herb in family Scrophulariaceae and its roots are a traditional Chinese medicine. The often-mentioned Six Flavor Rehmannia Pills [3] are one of the basic prescriptions in Chinese medicine. The origin of the name di huang (Rehmannia glutinosa) is mentioned in both Shennong's Classic of Materia Medica [4] and the Compendium of Materia Medica. The climate and soil of Taiwan are not suitable for growing it so most of the Rehmannia glutinosa sold in Taiwan comes from Henan Province in China. Rehmannia glutinosa differs in appearance and effect depending on how it is prepared. The three main types of Rehmannia glutinosa are:

 Raw Rehmannia glutinosa:  after picking the stem‚ leaves and fibrous roots are removed.

 Dried Rehmannia glutinosa : it is sun-dried after picking.

 Cooked Rehmannia glutinosa: raw Rehmannia glutinosa is steamed after mixing it with wine and Fructus amomi [5] ; after being steamed until well done it is then sun-dried.


In terms of nature and taste‚ raw Rehmannia glutinosa is “cold” and bitter sweet‚ and has a cooling effect and stimulates saliva production; dried Rehmannia glutinosa is sweet and has a heat dissipation and blood cooling effect; cooked Rehmannia glutinosa is warm and sweet‚ nourishes the yin and strengthens the blood. As well as being made into Chinese medicine and being mixed with other Chinese medicinal herbs‚ Rehmannia glutinosa can also be used in cooking‚ to boil eggs‚ stew chicken or make wine. Rehmannia glutinosa juice is the juice of raw Rehmannia glutinosa (can add lily) that has been boiled; it is effective for nourishing the yin and dissipating heat [6] .


When the Chinese mesona blooms


Chinese mesona (Mesona chinensis) is an annual herb in Family Lamiaceae. It has oblong leaves which are covered with fine hairs. It blooms in autumn. The light purple flowers have racemes [7] made up of umbels [8] and have an unusual appearance. Guanxi Township in Hsinchu County is one of the main production centers for Chinese mesona in Taiwan; the harvest takes place in September-October. The plants are harvested before they bloom and then a series of sun-drying stages follow. The dried Chinese mesona is then simmered over a low heat and becomes highly aromatic Chinese mesona juice.


When they hear the name Chinese mesona many people will think of the cooling green grass tea or herbal jelly of summer. Actually‚ as well as being made into drinks and snacks loved by many‚ Chinese mesona is also used as Chinese medicine and has a het clearing and cooling effect. Occasionally hawkers can be seen selling dried Chinese mesona from small trucks by the roadside‚ bringing back nostalgic memories for many people.
