Galactagogues

Galactagogues are simply foods, herbs or pharmaceutical drugs that promote the flow of a mother’s milk.

Ten steps to successful Breastfeeding (WHO)The day after my son was born, the hospital lactation consultant dropped by to tell me that I needed to top up with formula because I wouldn’t be able to make enough milk for him. It sounds brutal and blunt because it was. At the time I didn’t know that all the reasons her “diagnosis” was misguided and unhelpful so I delved into the world of galactagogues to help with low supply. Five months on, and Baba continues to be exclusively breastfed with comfortable weight gain. As an aside, I think it’s wrong to encourage pregnant women to breastfeed and tell them all the benefits but then provide no helpful support when we hit a roadbump (as most people would with any new skill).

Galactagogues are only part of the solution for boosting supply and should always be used alongside the support of a good, experienced lactation professional who can help with latch, technique etc. There’s also great information available from Breastfeeding Inc that can help with a range of breastfeeding issues.

Here is my experience with some of the common galactagogues:

  • Fenugreek (Trigonella foenum-graecum) seed is probably the most common and oldest documented medicinal herbs and is used for humans and cows throughout the world. Kellymom has summarised the dosage recommendations here. It is usually taken with blessed thistle and the two work well together. My own experience is that it worked well at 7g per day to improve supply but the gastric upset was so severe for both baby and me that we did not continue.
  • Fennel (Foeniculum vulgare) is often quoted as a galactagogue but in face it will not boost supply but will improve the milk ejection (let down). It’s a sweet tasting tea that helps with gas and digestion and tummy upsets so I’ve continued using it for these purposes rather than to boost supply
  • Similar to fennel, caraway is another anti-colic and anti-flatulent herb. It is often combined with other herbs when used as a galactagogue. I’ve enjoyed it with fennel as a tea.
  • Moringa (Moringa oleifera)– when I stopped fenugreek, I started taking moringa powder. It’s a good source of vitamins and minerals but more importantly it is well proven to boost milk supply. In my experience, it has been very effective.
  • Milk Thistle (Silybum Marianum) is usually associated with liver cleansing and gall bladder but it can also be used as a galactagogue. I’ve took this in the initial three weeks as a tincture in combination with Shatavari (Asparagus Racemosus), another popular galagtagogue
  • Nettle (Urtica dioica) – I’ve been taking dried nettle throughout pregnancy for its high iron content (and helps improve the body’s ability to use iron) and continued after birth. It is often used in combination with other herbs as a galactagogue. I’m a big fan of nettles and find that there are very few problems that can’t be helped with some nettles. It really is a wonder herb.
  • Red raspberry leaf (Rubus idaeus) is another favourite of mine and was something I was taking when there was new growth on our raspberry stems but as they’ve aged, I haven’t continued. It in itself is not a galactagogue but makes a nutritious and tasty tea and helps with let down.
  • Oats can be used as a food for lactating mothers. I’m not convinced of its galactagogue properties but porridge, breads, cookies etc are all good sources of healthy energy. I use oat groats soaked overnight rather than oat flakes to get the nutrition of the whole grain
  • And finally I tried taking Brewers Yeast as a powder and in cookies but again, the gastric upset was severe and not worth it.

So to summarise, I initially took milk thistle and shatavari as a tincture for three weeks to get things started. I tried both fenugreek and brewers yeast but found them difficult to digest. Now am taking dried nettle leaf, dried nettle seeds, oats, moringa powder and fennel/caraway as my milk boosting programme. I also take an Omega3 to help with the fat content of the milk and for general health.

On the anti-galactagogues, I’ve avoided ingesting mint and sage as well as using cabbage leaves topically (which is recommended by an astounding number of people).

There can be many reasons for low supply. A good latch and proper drainage are the basis for improving supply. There’s no substitute for proper support from knowledgeable and caring lactation professionals  but the herbs can definitely help.

 

 

Health benefits of Rooibos

The health benefits of tea are constantly mentioned in the media and a lot of people seem to start drinking tea (especially green tea and herbal teas) for health reasons. So, from time to time, I gather and review the research that is published.

Rooibos is a caffeine-free tisane that comes from the leaf of Aspalathus linearis. Since it does not come from Camellia sinensis it is not a real tea so we call it a herbal tea or tisane. Traditional medicinal uses of rooibos have included alleviation of infantile colic, asthma, allergies, dermatological problems, digestive discomfort and anxiety.

Many studies have been done on the antioxidant content of Rooibos. Marnewick found that a 200ml serving of Rooibos has 58.5 – 68.9mg of pholyphenol antioxidants (depending on amount of leaves used and brewing time). Studies on the chemical constituents of the antioxidants in Rooibos have shown the presence of nothofagin, aspalathin and isoorientin, orientin, rutin and several other flavonoids and phenolic acids. The types of polyphenols in Rooibos are different to those in Green tea and Black tea and in particular, the antioxidant aspalathin can not been found in any other natural sources besides Rooibos. Researchers have found that “an aspalathin-enriched extract of green rooibos is able to lower raised glucose levels in the blood of diabetic rats” (source).

Two of Rooibos’s antioxidants (quercetin and luteolin) have been shown, in vitro, to induce the death of cancer cells (in vitro just means that the tests were carried out in a controlled environment outside a living body, e.g. in a test tube). Rutin has been found to prevent the formation of thrombosis (blood clots) in mice and orientin has been associated with a reducing damage to the bone marrow and gastrointestinal tract after mice were exposed to radiation.

Although, the antioxidant content of Rooibos is well documented and there are many laboratory results on the benefits of those antioxidants, I found it very difficult to find scientific, peer-reviewed articles on human studies involving Rooibos. One paper, published in the Journal of Ethnopharmacology, looked at the effect of Rooibos on specific parameters for adults at risk of developing heart disease. The results were positive and Rooibos significantly improved the lipid profile and the redox status. However, just 40 participants were involved in the study so presumably it would need to be repeated with a much larger group before it could be cited as conclusive evidence.

Rooibos has long been used to soothe colic in babies but the tea gained particular attention in the late 1960s when a South African woman, Annique Theron, found that it eased her infant’s colic. The story goes that she found no documentation on the benefits of Rooibos so she began her own experiments with babies who had colic and allergies. She concluded that Rooibos helped with the symptoms and she published a book in 1970 entitled “Allergies: An Amazing Discovery”. Rooibos seems to be still recommended by South African physicians in the treatment of colic even though the scientific evidence as a treatment does not seem to exist. Similarly, there is no scientific research into Rooibos as a treatment for skin allergies or digestive problems but its use as a treatment for both seem widely accepted.

Rooibos NaturalSo what’s the bottom line on the health benefits of Rooibos? Well, Rooibos is naturally caffeine-free, calorie-free, low in tannins and rich in antioxidants. Some lab and mouse work have been done on the specific benefits of the antioxidants in Rooibos but research on human models is scant. I think Ferreira et al put it best when he said “the growing body of evidence pointing towards the therapeutic value of Rooibos tea gives a considerable degree of credibility to the anti-ageing claims, but expectations of a healthier life rather than increasing lifespan would perhaps be a more realistic outlook”.

Rooibos health updates

I have written previously about some of the research on rooibos but since then I came across a few new pieces:

  1. A study looking at the potential of Rooibos to increase the shelf life of Ostrich meat patties!
  2. A piece of on-going research involving the influence of Rooibos on prostate cancer.
  3. A study on the liver-related benefits of Rooibos and Red Palm Oil that was published in Evidence-Based Complementary and Alternative Medicine.

The press releases around the last one grabbed my attention by saying that this research proved that rooibos could improve liver function and protect against oxidative damage to the liver.

The inclusion of Red Palm Oil (RPO) in the title sent me off on a tangent to find out more about it. This in turn led to a diversion down the road of Palm Oil and Oxidised Palm Oil. Several hours later I had lost most of Saturday and was so far down a byroad of nutritional science that I didn’t think I would ever find my way back.  But the detour did turn up some interesting information albeit mostly unrelated to rooibos or tea.

It seems that palm oil comes from the palm fruit and is popular with food manufacturers because it is cheap and after processing has a long shelf life, is odourless and is solid at room temperature.  Oxidised palm oil is commonly used in food products and the oxidation seems to be responsible for the generation of toxicants and the introduction of “reproductive toxicity and toxicity of the kidney, lung, liver and heart” (Edem, 2002).

Red palm oil on the other hand comes from the same part of the palm tree but is red in colour from its high concentration of carotenes. Unprocessed, it contains high amounts of antioxidants and is associated with cardiovascular and nutritional benefits. At moderate levels, RPO is believed to promote the utilisation of nutrients, improves immune function and activate hepatic drug metabolising enzymes (Oguntibeju, 2009). Nutritional supplementation seems to show promise in lowering LDL cholesterol and experiments on rats show improved protection of the heart. [For entertainment see Dr Oz’s dramatic endorsements of RPO].

This new rooibos study worked from the basis that both rooibos and RPO had been shown to be liver-protective and it aimed to investigate if the positive effect could be heightened by combining rooibos and RPO. The results suggested that rooibos and RPO both protect the liver but the level of protection was only equal to that of either rooibos or RPO so a synergy in the combined protective effects could not be shown. Unfortunately, the study was carried out on rats so we still can not say for sure that a similar liver-protection effect happens when humans drink rooibos.

In fact, the only report involving rooibos and human liver that I found was a report in the Eur J Clin Pharmacology about a 42 year old patient with a previous medical history who experienced signs of liver damage after starting to drink rooibos. Clearly, a single case is not a basis for any kind of conclusion but it does indicate once again the need for human studies to confirm health benefits.
