Dendrobium is the stem of the orchid plant Dendrobium nobile. It got its name because it grows on rocks. Dendrobium hu is an ancient unit of capacity. As for why it is called dendrobium, Xiaoyong has not found out yet.

Dendrobium is an epiphytic herb. In addition to growing on rocks, it also grows on tree trunks. The fibrous roots attached to the rocks absorb moisture from the rock formations to provide nutrients, and the fibrous roots exposed in the air can also absorb moisture in the air.

Chinese medicine pieces are slices of dried stems of dendrobium. The dried dendrobium is golden in color and shaped like a hairpin, hence its name.

There are many types of Dendrobium. In addition to Dendrobium nobile, the stems of Dendrobium ringicae, Dendrobium candidum, Dendrobium huangcao, and Dendrobium viridis are also used as medicine.

Dendrobium has a strong vitality and grows on rocks. It grows by adsorbing water. Even if it is cut into short strips, it can bloom at a suitable temperature. The ancients took advantage of this characteristic of dendrobium and used it to nourish yin fluid.

Dendrobium also has the effect of clearing away asthenia and heat. It is a tonic medicine.

Dendrobium enters the stomach meridian and can nourish stomach yin. It is suitable for people who lack stomach yin and are hungry and have no desire to eat.

This type of person knows they are hungry but does not want to eat or does not eat much. Traditional Chinese medicine calls it stomach yin deficiency. It is like a pot with little water and can only cook very little rice and cannot hold too much food. .

In this case, dendrobium is the most suitable. Master Li Yuqi often uses dendrobium to nourish stomach yin.

Dendrobium can also enter the kidney meridian, nourish kidney yin and strengthen muscles and bones. The ancients believed that dendrobium grows on stones and has a hard body, which can nourish weakness, strengthen muscles and bones. "Shen Nong's Materia Medica" claims that it can "remove numbness"; "Famous Doctors" states that it can: "remove pathogenic heat and prickly heat from the skin, and cause pain and cold numbness in the feet and knees."

Later, doctors also took advantage of Dendrobium’s ability to nourish kidney yin and used it to treat blurred vision caused by liver and kidney yin deficiency, and created the famous Dendrobium luminous pill.

Herbs with flowers, leaves and stems contain volatile oils and are often lightly decoctioned for medicinal purposes, but dendrobium is an exception. The active ingredients of dendrobium are alkaloids, which are difficult to dissolve in water and require a long period of decoction when used in decoction.

How long does it take to fry?

At least half an hour. Some people have done experiments and found that more than 90% of the active ingredients are cooked out after one hour of decoction.

It would be better if fresh dendrobium can be used for natural effect. It is precisely because the active ingredients of dendrobium are difficult to separate out, the ancients also advocated boiling dendrobium for a long time to make a paste.

During the Qianlong period, Mr. Huang Gongxiu wrote in "Materia Medica Seeking Truth":

Nowadays, Dendrobium officinale tea is very popular, and its efficacy is similar to that of the traditional Chinese medicine Dendrobium. But if you drink it as tea, you cannot simply brew it. It is best to simmer it for half an hour before drinking it to see the effect.

In fact, dendrobium has been used in tea for a long time, but have you heard of this use?

Ten grams of dendrobium and 1 piece of ginger, decoction in water instead of tea, can clear the lungs and nourish the spleen. Dendrobium nourishes the spleen and stomach, and also clears the lungs. Li Shicai's "Compendium of Materia Medica Tongxuan" of the Ming Dynasty said that "the ancients used it as a substitute for tea, and it was very clear on the diaphragm."

In addition to the Golden Throat throat medicine, ordinary people use Ophiopogon japonicus and Pestria striata to clear their throats. In fact, the more sophisticated ones use dendrobium. Because dendrobium requires a long time to cook, many people are impatient and don’t persist much.

It is said on the Internet that old Beijing opera singers such as Mei Lanfang, Ma Lianliang, and Tan Fuying use dendrobium instead of tea to protect their throats all year round. Xiaoyong didn’t go to verify it, so it’s probably true.

Traditions are interlinked, and the elders probably know something about Chinese medicine. If you are a teacher or rely on your voice for a living, you might as well be patient and try slow-cooking dendrobium every day to protect your voice.
