Alfalfa (Medicago sativa)
Suggested Dosage: Capsules up to 4 capsules, 3 times a day
Homeopathic 6 tablets per day
Side Effects: At customary dosage levels, Alfalfa leaf poses no problems.
There have been isolated reports of persons allergic to alfalfa.
Not recommended for use by persons taking blood thinning agents.
Ingestion of large amounts of the seed and/or sprouts has been linked to the onset of systemic lupus erythematosus (SLE) in animal studies. The chemical responsible for this effect is believed to be canavanine. Persons with SLE/lupus or with a history of lupus or other auto-immune disorder should not use alfalfa products, as they have been known to aggravate lupus and other auto-immune disorders.
Other Notes
Alfalfa is one of the more commonly used galactagogues. Can be taken in combination with blessed thistle, marshmallow, and fenugreek.

Homeopathic remedy: I've seen a recommendation to take alfalfa in combination with Lactuca Virosa. After taking this combination, some women have noticed an increase in milk supply of 50-100%. More information on alfalfa (in general, not as a galactagogue) can be found here:


Contains estrogenic precursors and has lots of vitamins and minerals in absorbable form.
Start with 1 capsule 4 times a day and work up to 8 capsules a day. If stools get too loose stop and only use 1 dose less. You should end up taking 2 tablets 4 times daily.

Alfalfa is thought to dramatically help bring the milk in for the nursing woman. It enriches the quality of the milk and is much preferable to other hot beverages, such as regular tea, which can pollute the breast milk. It can be flavored with orange peel, and honey. Or you can get it in pill form. Alfalfa is one of the few vegetable sources of Vitamin D.  There are about 4740 International Units of Vitamin D per pound of Alfalfa. This is valuable knowledge if a person is unable to take the sun, such as during the wintertime. Taking Vitamin D in Alfalfa is much healthier than drinking it in pasteurized, homogenized, Vitamin-D enriched milk! 

A deep-rooted perennial plant of the pea family. The erect, smooth stem grows from an elongated taproot to a height of 12 to 18 inches.  Contains organic minerals such as calcium, magnesium, phosphorus, and potassium and almost all known vitamins, as well as very high in chlorophyll.

First discovered by the Arabs, who dubbed alfalfa, this valuable plant, as the "father of all foods." According to an early Oriental herbarium, alfalfa tops the list of 896 plants cited, and originated in Persia. Alfalfa, a native of Asia, didn't reach North America until around 1850 or 1860. Native Americans adapted alfalfa quickly for human use, as well as for animals. In England and South Africa it is called Buffalo herb.

Warning:  Alfalfa has been known to aggravate lupus and other auto-immune disorders. Avoid alfalfa is you have an auto-immune problem. 

Goat's Rue
Suggested Dosage: Tincture 1-2ml 3X/day
Infusion Add 1 cup of boiling water to 1 tsp dried leaves. Infuse for 10-15 minutes. Drink 1 cup 2 times per day.
Side Effects: diaphoretic (can increase sweating)
hypoglycemic (can cause a drop in blood sugar)
has an unpleasant flavor and can nausea to some people.
in excess, can cause nausea, vomiting, irritation and inflammation of the stomach and bowels
not for use during pregnancy
Other Notes Goat's Rue has been reported to be a galactagogue. It may stimulate production of mammary glands. The botanical name is Galega Officinalis or Galega Virginiana. It is also known as French Lilac. It was first used as a galactologue by French dairy farmers, who noted a 35-50% increase in their cow's milk output. One mom reported a doubling of her pumping supply when taking this tincture. Goat’s rue contains galegin, which has a hypoglycemic action similar to those of synthetic guanidine derivatives.
This herb should be used with caution, under the direction of a qualified herbalist or other health care adviser. Dosing should begin very low, such as 5 drops, and slowly work up one drop at a time to a maximum of 15 drops three times a day.


Herbs for increasing milk supply
These herbs have been shown to help increase milk supply and quality of the milk...

Anise/Aniseed (Pimpinella anisum)
Suggested Dosage: Capsules Unknown
Homeopathic Unknown
Infusion Crush seeds just before use. Poor 1 cup of boiling water over 1-2 tsp of seeds. Let stand covered for 5-10 minutes. Drink 1 cup 2-3 times per day.
Side Effects: Anise poses no known risks when taken at customary dosage levels.
There is a slight possibility that you could develop an allergic sensitivity to the herb.
Not recommended for use during pregnancy.
If you should not take birth control pills containing estrogen, do not take Anise–it has some estrogen-like activity.
Other Notes Anise seed is one of the more commonly used galactagogues. Anise seed cookies are traditionally brought to new mothers in some cultures. Anise is also reported to be helpful for infantile colic. Other names are Sweet Cumin, Star Anise, Chinese Anise, Illicium.

Astragalus root (Huang-qi)
Suggested Dosage: Capsules unknown
Homeopathic unknown
Infusion unknown
Side Effects: Astragalus appears to be relatively nontoxic. High one-time doses, as well as long-term administration, have not caused significant harmful effects.
Side effects are rare and generally limited to the usual mild gastrointestinal distress or allergic reactions.
Other Notes This herb is widely used in Chinese Traditional Medicine. Reported toxicity is very low. From the information that I have, this appears to be safe for nursing moms. Three species of Astragalus have been reported to increase milk supply - A.glaux from the Mediterranean, A. glycyphyllos from the Ukraine, and A. hamosus from India.

Blessed Thistle (Cnicus Benedictus)
Suggested Dosage: Capsules up to 4 capsules, 3 times a day
Tincture up to 20 drops of tincture, 2-4 times daily
Tea Pour one cup of boiling water over 1.5 to 2 grams of crushed Blessed Thistle and steep for 10 to 15 minutes. Drink 1 cup 2-3 times per day.
German Commission E monograph recommends 4–6 grams of blessed thistle per day.
Side Effects: Anyone with allergies to plants in the daisy family should use blessed thistle cautiously.
Reported to be an effective emmenagogue. The American Herbal Products Association Botanical Safety Index and the German Commission E indicate that blessed thistle is not to be used during pregnancy.
Cathartic (laxative effect) and emetic (causes vomiting) in large doses (more than 5 grams per dose).
Other Notes Blessed thistle is one of the more commonly used galactagogues. Can be taken in combination with red raspberry, alfalfa, marshmallow, and fenugreek.

Borage
Suggested Dosage: Capsules Unknown
Side Effects: mild laxative
potentially toxic
The American Herbal Products Association Botanical Safety Index indicates that borage is not to be used during pregnancy or while nursing.
Borage is not recommended for long term use.
Other Notes

Borage leaves, when prepared properly, appear to be an effective galactagogue. There is at least one tincture designed for increasing milk supply that contains borage (among other things) that is commercially available . Use this herb with care - it might be best to ensure that it's prepared by an experienced herbalist.


Dill
Suggested Dosage: Food Additive use two teaspoons of raw dillseed on your lunch and dinner, or brew a tea (see below)
Side Effects: At usual dosage levels, dill poses no health hazards.
Contact with juice from the fresh plant can make your skin react badly to sunlight
Other Notes Dill is considered by some to be a galactagogue. It is a common culinary herb.
Dill tea: Steep 2 teaspoons of dill seed in 1 warm cup of water for 10-15 min. Take 1/2 cup 2-3 times daily.
Another recipe (reported to be an old Indian remedy for low milk supply):
Steep 1/2 cup dill seeds in water overnight. Boil until very dark in color. Strain. Drink one cup of this dill tea per day.

Essential Fatty Acids / Flaxseed Oil
Suggested Dosage: Unknown
Side Effects: None Known
Other Notes One midwife suggests taking an essential fatty acid supplement, because the fatty acids help us to make the hormones we need for breastfeeding. She suggests trying it for at least a week. Reportedly, some moms have had luck with this, especially if they are on a really low fat diet.

Flaxseed oil is rich in omega-3 essential fatty acids, and is reported safe for nursing moms.

Fennel
Suggested Dosage: Infusion Use 1/2-2 tsp crushed seeds in 1 cup of boiling water. Let sit for 10-15 minutes. Drink 2-3 cups per day.
dosage-breast massage oil: Use one drop of fennel oil added to a teaspoon of olive oil. This should be used with great caution, as it is unsafe for baby to ingest fennel oil.
Do not ingest fennel oil or allow baby to ingest it. It can be toxic in doses greater than about a teaspoon, and can cause miscarriage in pregnant women.
Side Effects: Small amounts of fennel are safe when the seeds or fruits from the fennel plant are used.
possible side effects include allergic reactions or dermatitis
can act as an appetite suppressant
if taken in excess, can decrease milk supply, as fennel contains phytoestrogens
Oil from the fennel plant should be avoided. This volatile oil is toxic and can cause seizures and respiratory problems in doses as small as 1 to 5 milliliters (less than 1 teaspoon). Do not ingest fennel oil or use it anywhere that baby may ingest it
Other Notes Fennel (Foeniculum) is a common galactagogue. It tends to promote the milk ejection reflex (letdown), rather than actually increasing milk supply. Fennel may be a good choice for working mothers who are experiencing decreasing pump output. Fennel contains EFAs flavonoids, vitamins, minerals, and volatile oils. It has been used for gastrointestinal disorders and as an expectorant, and can be a diuretic.

Fenugreek ( Trigonella foenum-graecum L. )
Suggested Dosage: Capsules (580 - 610mg)
  • 2-4 capsules, 3 times per day
  • 6-12 capsules (total) per day
  • ~1200-2400 mg, 3 times per day (3.5-7.3 grams/day)
  • German Commission E recommends a daily intake of 6 grams
Capsules (500 mg)
  • 7-14 capsules (total) per day
Powder or Seeds
  • 1/2 - 1 teaspoon, 3 times per day
  • 1 capsule = 1/4 teaspoon
  • can be mixed with a little water or juice
Tincture
  • 1-2 mL, 3 times per day (or see package directions)
Tea
  • one cup of tea, 2-3 times per day
Side Effects:
  • Sweat and urine smells like maple syrup; milk and/or breastfed baby may smell like maple syrup.
  • Occasionally causes loose stools, which go away when fenugreek is discontinued.
  • Use of more than 100 grams of fenugreek seeds daily can cause intestinal distress and nausea (recommended dose is less than 8 grams per day).
  • Repeated external applications can result in undesirable skin reactions [Wichtl 1994].
  • Ingestion of fenugreek seeds or tea in infants or late-term pregnant women can lead to false diagnosis of maple syrup urine disease in the infant due to presence of sotolone in the urine. See [Korman 2001] and other studies on fenugreek and maple syrup urine smell.
  • Peanut or chickpea allergy: Fenugreek is in the same family with peanuts and chickpeas, and may cause an allergic reaction in moms who are allergic to these things. Two cases of fenugreek allergy have been reported in the literature. [Patil 1997, Ohnuma 1998, Lawrence 1999]
  • Diabetes or hypoglycemia: Fenugreek reduces blood glucose levels, and in the few studies using it as a hypoglycemic, also reduces blood cholesterol. Dosages higher than the recommended one (given above) may result in hypoglycemia in some mothers [Heller]. If you're diabetic (IDDM), use fenugreek only if you have good control of your blood glucose levels. While taking this, closely monitor your fasting levels and post-prandial (after meals) levels. Mothers with hypoglycemia should also use fenugreek with caution. For more on fenugreek and glucose levels, see the references below.
  • Asthma: Fenugreek is often cited as a natural remedy for asthma. However, inhalation of the powder can cause asthma and allergic symptoms. Some mothers have reported that it worsened their asthma symptoms. [Dugue 1993, Huggins, Lawrence 1999].
  • Abnormal menstrual cycles: Fenugreek is considered to be an emmenagogue (promotes menstrual flow). Per [White], it may cause breakthrough menstrual bleeding; this source recommends using fenugreek with caution if you have a history of abnormal menstrual cycles.
  • Migraines: Fenugreek is often cited as a natural remedy for migraines. However, [White] indicates that it may trigger a migraine and/or contribute to the duration and severity of a migraine.
  • Blood pressure problems or heart disease: Fenugreek is commonly reported to lower blood pressure and LDL blood cholesterol levels. [White] indicates, however, that it may cause or contribute to hypertension (high blood pressure) - this source recommends avoiding this herb if you have a history of hypertension, or if there is a strong family history of hypertension or heart disease.
  • Oral drugs or herbs taken at the same time as fenugreek may have delayed absorption due to the mucilage content of fenugreek. [Wichtl 1994]
  • Glipizide and other antidiabetic drugs
    Fenugreek reduces blood glucose levels and may enhance the effects of these drugs.
  • Insulin
    Fenugreek reduces blood glucose levels, so insulin dosage may need to be adjusted.
  • Heparin, Warfarin and other anticoagulants
    Ticlopidine and other platelet inhibitors
    The fenugreek plant contains several coumarin compounds. Although studies have not shown any problems, it potentially could cause bleeding if combined with these types of drugs.
  • MAOIs
    Fenugreek contains amine and has the potential to augment the effect of these drugs.
Other Notes Fenugreek has been used traditionally to treat diabetes, coughs, congestion, bronchitis, fever, high blood pressure, headaches/migraines, diarrhea, flatulence, anaemia, irregular menstrual cycles and arthritis, to ease labor pains and menstruation pain, and as an appetite stimulant. Fenugreek has also been used as an external poultice to control inflammation and dandruff.

Ignatia
Suggested Dosage: Tablets two tablets of Ignatia 6X, taken three times per day
Side Effects: none known
Other Notes This is a homeopathic remedy for increasing milk supply. Reported to be more effective when taken with a mild galactagogue such as nettle.

Lactuca Virosa
Suggested Dosage: Capsules / Homeopathic 2 pills (30c or 200c), 2x/day.
Side Effects: The fresh herb is a strong sedative when taken in large doses. Should be avoided during lactation due to possible sedative side effects to the baby.
The homeopathic version has no side effects (including sedation).
Other Notes

Homeopathic remedy: I've seen a recommendation to take alfalfa in combination with Lactuca Virosa. After taking this combination, some women have noticed an increase in milk supply of 50-100%.

Lactuca Virosa is also known as wild lettuce. It can be ordered in different strengths in homeopathic pill form (under the tongue). Some people have had a problem finding this -- Washington Homeopathic Products, Inc. carries it.


Marshmallow
Suggested Dosage: Capsules up to 4 capsules, 3 times a day
Side Effects: There have been extremely rare reports of allergic reactions.
Diabetics should be mindful of the sugar concentration of Marshmallow syrup
Other Notes Marshmallow appears to be a nourishing herb, not a galactagogue.
However, at least one mom who I know of has seen better results using a combination
of fenugreek/marshmallow rather than fenugreek alone.
Can be taken in combination with blessed thistle, alfalfa, and fenugreek.

Milk Thistle (Silybum marianum)
Suggested Dosage: 12-15 grams (about 1 Tablespoon) of crushed seeds per day. This is the equivalent of 200–400 mg of silibinin.
Side Effects: Since one constituent does stimulate liver and gallbladder activity, it may have a mild, transient laxative effect in some individuals. This will usually cease within two to three days.
Allergic reactions have been reported
Other Notes Milk Thistle Milk thistle has been used historically to increase milk supply. It contains silibinin, silydianin, and silychristin, which supposedly have liver-protecting properties

Mother's Milk Tea
Suggested Dosage: Tea 3-4 cups per day
Side Effects: See individual herb listing
Other Notes

You can find mother's milk tea in many health food stores. Different brands have different ingredients, but I believe that most contain fenugreek, fennel, nettle and/or blessed thistle. Following is one recipe.

All-purpose nursing infusion: 1 ounce dried blessed thistle or borage leaves, 1 ounce dried raspberry or nettle leaves, 1 teaspoon any one of these seeds: anise, cumin, fennel, caraway, coriander, dill. Place leaves in half gallon jar and fill to top w/ boiling water. Cap tightly and steep overnight. Strain herbs and refrigerate until needed. Before nursing, pour off one cup and heat nearly to boil. Pour over a tsp. of any of the seeds. Let brew and cool for five minutes before drinking. Can be drunk freely, up to two quarts a day. ("Wise Woman Herbal for the Childbearing Year" by Susan Weed)

To make another milk boosting tea, use 1 teaspoon *each* of fennel, cumin and dill, steeped in 8 oz of boiling water for 15-20 minutes. Drink one cup, three times a day. Results should be noticeable within 24 hours. Then you can increase or decrease frequency as needed.


Nettle (Urtica dioica)
Suggested Dosage: Tea see below
Side Effects: mild diuretic
Other Notes

Nettle (Urtica dioica) is a well known galactagogue. It's sometimes found in mother's milk teas, and can also be found as nettle tea or as a tincture. MotherLove sells a tincture called More Milk, which contains tincture of blessed thistle, nettles and fennel seed. Nettle leaves are also a good source of iron, calcium and vitamin K. Other uses for nettle include easing leg cramps and other muscle spasms (since it is high in calcium) and preventing hemorrhage after birth (since it is high in Vitamin K and iron).

Nettle tea can be made by pouring one cup boiling water over 2 teaspoons of herb and allowing it to seep for 10 minutes. Drink 2-3 cups per day. This is recommended as a strengthening, nourishing tonic.

*** Please check the label for ingrediants in the tea. Many contain mint for flavor, which is an anti-galactogogue. ***

Oatmeal
Suggested Dosage: One bowl of hot oatmeal (any type) every day.
Side Effects: Oats are not associated with any adverse effects
Those with gluten sensitivity (celiac disease) should eat oats with caution
Other Notes

Eating a bowl of oatmeal for breakfast each morning commonly has been recommended as a way to increase milk supply, and it does seem to work. In some countries, "traditional wisdom" recommends eating oatmeal as a way to increase milk supply. In addition, some working moms have noticed that on the days they eat oatmeal for breakfast, they can pump more milk than on the days they eat something else. A number of lactation consultants recommend eating oatmeal (sometimes in combination with herb use) as a way to increase supply.

Some possible explanations:

Fenugreek is recommended for stomach issues and cholesterol problems, among other things. Blessed Thistle and fennel are recommended for digestive problems. Alfalfa is recommended for digestive problems and high cholesterol. Metoclopramide and domperidone (prescription drugs that increase supply) also have actions related to the stomach. All are used for milk supply. Oat bran, which is in oatmeal, is known to help lower cholesterol. These are loose ties, but possibly significant.

Oatmeal is high in iron, and therefore especially helpful for moms who have had a major blood loss, or for other reasons dropped their Hgb and Hct. The increased nutritional status for mom might result in better milk supply.

Oatmeal is also a comfort food for many women: if it increases relaxation in mom it can encourage letdown and perhaps even milk supply.

Eating a bowl of oatmeal at the very least would do nothing. If it turns out to be helpful, it's a really easy way to increase supply!


Red Clover
Suggested Dosage: Unknown
Side Effects: Non-fermented red clover is relatively safe.
Fermented red clover should be avoided altogether.
Not to be used during pregnancy or by persons taking blood thinning agents.
Other Notes Red Clover has been reported to bring in rich milk. I'm not aware of the recommended dosage.
I believe that it's not a galactagogue, but provides vitamins/minerals helpful for good milk production.

Red Raspberry Leaf
Suggested Dosage: Tincture 10-60 drops (4-8 mL) 1-4 times per day
Tea up to 6 cups per day
Side Effects: Raspberry may cause mild loosening of stools and nausea
Since it is a uterine stimulant, some recommend not using this herb during the first trimester of pregnancy, partuicularly if you have a history of miscarriage.
Contraindicated where there is a history of precipitate labors (under 3 hours).
Other Notes

Red Raspberry Leaf has been reported to bring in rich milk. I believe that it's not a galactagogue (though some report it as such), but provides vitamins/minerals helpful for good milk production.

Prepare tea by pouring 1 cup (250 ml) boiling water over 1–2 teaspoons (5–10 grams) of the herb and steeping for ten to fifteen minutes.
