Astragalus spp. (including membraneous) aka Huang Qi or Huang Ch'i aka

Yello milk vetch root.

 

According to Richo Chech at Horizon Herbs

http://www.chatlink.com/~herbseed/Welcome.html

" Cultivation: Easy. Sow seed in flat or better yet, direct seed in

early summer. Germination may be improved by soaking the seed in warm

water overnight before planting. Expect germination in 3-10 days.

Plant 1 foot apart

in average soil with good drainage. Prefers full sun. Plants grow to 4

 

feet tall. "

Its taste is sweet and energy is slightly warm and moistening. The

root/rhizome is what is used. Astragalus americana was used by Great

Plains tribes...and has a yellow and sweet root...but apparently it can

accumulate selenium so one may have to test for its presence. (Too much

selenium is toxic.)

 

Ron Teeguarden in " Chinese Tonic Herbs " calls astragalus an " energy

tonic " which affect the following meridians: Spleen, Lung and Triple

Warmer.

 

Teeguarden says, " Astragalus is believed to be strengthening to the legs

 

and arms, and is traditionally used by people who work outdoors,

especially in the cold, because of its strengthening and warming nature.

 

As an energizer to the outside of the body, Astragalus is used to tonify

 

the protective energy (Wei Ch'i) which circulates just under the skin.

Wei Ch'i is the Yang counterpart of the more Yin nutritional energy

(Ying Ch'i) which flows through the twelve meridians and supplies the

organs with vital energy. " (p. 98)

 

Astragalus is known as an adaptogen, immune tonic, diarrhetic,

hypoglycemic agent (helps lower blood sugar levels), nervine,

cardiovascular tonic, stops excess sweating and supports the lungs. It

can be very helpful in cases where there is a chronic weakness of the

lungs with shortness of breath, and prolapse of internal organs.

 

It works especially with the immune and endocrine systems. Look to use

it in cases where someone's immune system is not working up to pare,

where s/he has frequent colds, bronchitis, sweats easily--especially

night sweats.

 

Astragalus helps in cases where there are deficient stomach/spleen

patterns. That is, a person is fatigued with no appetite. For collapsed

chi--it is a major immune strengthening herb, useful in situations from

cancer to AIDS; situations where someone has frequent colds, bronchitis,

 

problems with their lungs.

 

With HIV infections, there is often insufficient chi and many sweat

abnormally.

 

Teeguarden says that an article in " Cancer, " a publication of the

American Cancer Society, reported that the aqueous extract of Astragalus

 

membranaceus restored the immune function in 90 percent of cancer

patients studied. Basically, it has been shown to work very well in

strengthening cancer patients' immune systems. The same studies showed

the herb promoted adrenal cortical function, ameliorated bone marrow

depression and the gastrointestinal toxicity caused by chemo and

radiation therapies.

 

Astragalus increases strength and activity of the endocrine system. It's

 

useful for adult onset diabetes. Furthermore, it increases peripheral

circulation to the skin.

 

This herb can also be used for damaged lungs--emphysima, asthma, other

deficient lung conditions (used with other herbs to balance the body

system.)

 

In cases of fire poison, where there are boils and styes full of pus but

 

they won't open and clear...it will encourage them to come to a head,

open and heal more quickly.

 

By stir frying the herb, it will be more tonifying to the lung. Stir

fried in honey, it will work more to increase circulation. In rice wine,

 

it will be directed more toward the kidneys.

 

Dosage: 2 teaspoons of herb to one cup (8 oz.) water, decoct 4 hours or

more. Take 2 to 3 cups per day. This is really better prepared and taken

 

as a decoction than tincture, although you can tincture it. Personally,

unless you're just going to be in a situation where you're traveling and

 

cannot prepare a decoction, I wouldn't bother with a

tincture....HOWEVER....

 

to make a tincture....cook the herb for 12 hours using a 1:5 ratio, that

 

is, one part astragalus to five parts water. Steep it for another 6 to 8

 

hours, then add 30 percent grain alcohol. Take 40 to 60 drops, three to

four times a day.

 

By the way, Bob Flaws, who has written extensively on TCM, has a book

called " Chinese Medicinal Wines & Elixirs " in which he gives a simple

recipe for astragalus wine that does not include decocting it.

 

CONTRAINDICATED: (do not use) Do not use astragalus by itself in

situations where there is " heat in the Lung " or damp heat in Spleen).

agree with everything they say here (as in, the herb is not

recommended for people who already have a cold), but mostly

it seems really good.

Thanks for some very good and thorough info on astragalus.

 

I want to use this post as an opportunity to review some things. I also

want to add some info.

 

>For pictures of a variety of species of Astragalus, go to

>http://loco.ucdavis.edu/astragalus/astragallery.htm

 

I had no idea there is so many species of astragalus. The Wicke Materia

Medica lists 5 species as Radix Astragali, aka Huang Qi. These are 1.

Astragalus membranaceus (Fisch.) Bge; 2. A. mongholicus Bge.; 3. A.

chrysopterus Bge.; 4. A. floridus Benth.; and 5. A. tongolensis Ulbr.

 

This is an herb that you want to be very, very careful in making sure that

you've got one of the species recognized as Radix Astragali or Huang Qi.

Just any speices of astragalus won't do. Among the many plants in the genus

Astragalus are some whose common name is " locoweed " . Yes. It's that stuff

you occasionally hear mentioned in Westerns. " Yep. Cattle done up and

died. Stumbled around, acted plum loco before they died. Must have gotten

into a patch of locoweed. "

 

BTW, one species of locoweed grows abundantly in the area I live in. It's a

very pretty plant. It blooms in the spring and provides a carpet of pinkish

purple blooms for a few weeks. I knew it was locoweed, but I didn't know

that this is one of the astraglus species until I read your post and looked

at some of the links.

 

>Its taste is sweet and energy is slightly warm and moistening.

 

Sweet tasting herbs will tend to be very moistening, but their energy most

often is mildly cooling. This is an example of a sweet-tasting herb which

has slightly warm energy.

 

>

>Ron Teeguarden in " Chinese Tonic Herbs " calls astragalus an " energy

>tonic " which affect the following meridians: Spleen, Lung and Triple

>Warmer.

 

One thing to be aware of when using Teeguarden's " Chinese Tonic Herbs " is

that he uses the word " tonic " in ways it's not usually used. There are a

relatively few herbs that are classified as Qi (energy), Blood, Yin, or Yang

tonics. Astragalus actually is a Qi tonic herb. One of the advantages of

the Teeguarden book is it shows pictures of herbs in their pharmaceutical

state. This can be a great help if you order herbs and need to check that

you got what was ordered. (Sometimes sight alone won't be enough, but

learning to visually recognize herbs can be a great help.)

>Wei Ch'i is the Yang counterpart of the more Yin nutritional energy

This is a very important point to remember about astragalus and often will

be one of the deciding factors in an herbalist using astragalus in a formula

instead of ginseng. Astragalus is one of the Qi tonic herbs that

specifically boosts Protective (Wei) Qi. If a person tends to catch a lot

of infections, has wounds that are not healing as quickly as they should, or

is very weather sensitive, these can be symptoms that the Protective Qi is

weak. Just any Qi tonic herb will not help Protective Qi as much as a Qi

tonic herb which specifically helps Protective Qi.

 

BTW, some authorities equate Protective Qi Deficiency with Lung Qi

Deficiency. If a person is Protective Qi Deficient you can bet the person

also has Lung Qi Deficiency.

 

>It works especially with the immune and endocrine systems. Look to use

>it in cases where someone's immune system is not working up to pare,

>where s/he has frequent colds, bronchitis, sweats easily--especially

>night sweats.

 

Wicke (vol. 2, p. 117) mentions that astragalus not only can be used in

cases of sweating due to Qi Deficiency but also can be used in cases of

sweating at night (Yin Deficiency) and in cases of Yang Deficiency sweating.

It also can be used in cases of inadequate sweating due to Exterior

pathogens, but you need to mix it with other herbs in the case of inadequate

sweating.

 

Astragalus appears to regulate sweating to normal sweating. Review:

Spontaneous sweating at unusual times can be a symptom of Qi Deficiency. In

a few cases it can also be a symptom of Yang Deficiency. When a person has

night sweats, this usually is a symptom of Yin Deficiency.

 

>Astragalus helps in cases where there are deficient stomach/spleen

>patterns. That is, a person is fatigued with no appetite.

 

Wicke also mentions that it will raise the Yang Qi of the Spleen. Review:

Spleen Qi is supposed to ascend. When it doesn't, problems like prolapsed

organs can result. Astragalus can be very helpful in treating Spleen Qi

Sinking. (More advanced info: Spleen Qi Sinking is classified as a

Deficiency problem. The cases of Qi rising when it should be descending or

rising too much are classified as Excess patterns.)

 

>For collapsed

>chi--it is a major immune strengthening herb, useful in situations from

>cancer to AIDS; situations where someone has frequent colds, bronchitis,

>problems with their lungs.

 

Remember the comments about one of the symptoms of Protective Qi Deficiency

being that the person can't fight off infections and catches a lot of

infections. And remember the comment about some authorities saying that

Protective Qi Deficiency equates with Lung Qi Deficiency. This can be

important to remember because in a few cases of Lung Qi Deficiency, the Lung

problems may not be that obvious. The person may not be catching frequent

infections like colds that would cause the healer to suspect Lung Qi

Deficiency. This doesn't happen very often, but you can run into a

situation where the person is very Protective Qi Deficient but not catching

a lot of colds. This happens quite a bit with PWCs. (People With CFIDS -

Chronic Fatigue Immune Dysfunction Syndrome). During one phase of the

CFIDS, the PWC will not catch colds. But the PWC feels like s/he has a bad

case of the flu all the time. When the PWC starts to improve, s/he will

start to catch colds again. This is an unusual situation that you won't see

a lot unless you specialize in knowing about CFIDS, but I want readers to be

aware that you can run into situations like this so you will know to suspect

possible Lung Qi Deficiency even thought the signs may be minor. BTW, PWCs

tend to be extremely weather sensitive no matter what phase of the CFIDS

they are in. If there are symptoms of Protective Qi Deficiency - like

extreme weather sensitivity - automatically consider that Lung Qi is

Deficient as well as Protective Qi. It can enable the healer to fine-tune

treatment even more that s/he would be able to.

 

>By stir frying the herb, it will be more tonifying to the lung. Stir

>it will be directed more toward the kidneys.

 

Review: How an herb is prepared can change its properties. For example

fresh ginger (warm and expels Wind Chill from the Exterior) and dried ginger

(hot and used to warm the interior) have different properties. So do cooked

rehmannia and raw rehmannia. BTW, honey, wine, salt, vinegar, etc. can be

used to either change the properties of an herb slightly or to direct it

more to a certain part of the body.

 

>CONTRAINDICATED: (do not use) Do not use astragalus by itself in

>situations where there is " heat in the Lung " or damp heat in Spleen).

 

Wicke words the contraindications as Deficiency of Yin with Heat (Yin

Deficiency with predominating symptoms of Heat) and Excess Heat (which

includes Damp Heat). Dampness automatically is classified as Excess.

Actually, this is standard advice with all the tonic herbs. Stop the tonic

herbs if the person comes down with a cold or the flu. Otherwise the tonic

herbs may strengthen the pathogen. There are exceptions to this rule.

Sometimes you wouldn't dare stop the tonic herbs because the person needs

them so much.

 

There are some special rules for dealing with colds and the flu. They're

covered in the 6 Stages of Cold-induced Evils. The treatment will vary

quite a bit depending on which stage the Evil is in. During the early

stage, it is proper to induce sweating. In later stages, this could hurt so

treatment is directed toward other things. " Early " and " later " are poor

words on my part. A person with a cold or flu and stay in one stage a long

time, go back to a stage, or even skip a stage.
