What is it?

In herbal medicine, we use all the dried aerial parts (leaves and flowers) of the beautiful Californian poppy, a herb that, as the name suggests, is the official state flower of California and is native to that area as well as to Mexico. Californian poppy is a drought-resistant herb that can be a perennial but grows best as an annual up to 1.5 metres in height and doing well with full sun in dry, sandy, drained and poor soil.




How has it been used?

Native American tribes used the leaves and flowers, of Californian poppy for their sedative and pain-relieving properties and for the relief of toothache, especially in children.

Thomas Bartram desribes Californian poppy's actions as hypnotic (sleep inducing), sedative, nerve relaxant and anodyne (pain-relieving) and recommends it for insomnia, migraines, stressful conditions, nervous bowel, anxiety, depression and neuralgia (nerve pain). He says it combines well with Passionflower for in equal parts for hyperactivity and sleeplessness and suggests doses of a tsp to a cup of boiling water.

Rudolph Weiss writes that 'like the opium poppy, it contains a number of alkaloids with hypnotic and sedative effects, for example protopine, cryptopine, and chelidononine, however the overall effect is mild, generally more balancing, and non-narcotic. It can be prepared as a tea (1 tsp per cup) and is tolerated well, even by children, where it is most commonly prescribed for treatment of childhood neuropathy (nerve pain) but also for nocturnal enuresis' (bed-wetting)

Californian poppy has traditionally been used for reducing pain and helping to promote calm sleep without the dangers of the more powerful opiates of the Opium poppy. Its muscle relaxing actions has seen it be especially used for children to help with the pain of colic or whooping cough.

It was of interest to medical practitioners in America in the late 19th century and was described in 1892 as 'an excellent soporific (sleep inducing) and analgesic (pain-relieving), which is above all harmless. The effect produced by Californian poppy is the same as that of morphine, without the inconvenience of the latter drug.'


Science on Californian poppy

~ Californian poppy, like the opium poppy, contains a number of isoquinoline alkaloids. These include such potent chemicals as californidine, eschscoitzine, allocryptopine, protopine, papaverine and noscapine. Although the narcotic effect of Californian poppy is much less potent than that of morphine or codeine it will still have pronounced sedative and hypnotic (sleep inducing) effects when taken in sufficient dosages. In moderate amounts, it can be seen to be non-sedating but still able to relieve neuralgia (nerve-pain).

~ The use of Californian poppy in two controlled clinical trials showed that it could normalise disturbed sleeping behaviour without any evidence of carry-over effects or addiction. (Schafer HL et al: Arzneim Forsch 45(2): 124-126, 1995)

~ A study combining California Poppy with Crataegus oxyacantha and measured against placebo in 264 patients with diagnosed General Anxiety Disorder of mild to moderate intensity over a period of three months showed statistically significant benefits associated with all parameters of Anxiety (assessed by Hamilton Anxiety Scores) on day 14, 60, and 90 (Hanus M, Lafon J, Mathieu M Double-blind, randomised, placebo-controlled study to evaluate the efficacy and safety of a fixed combination containing two plant extracts (Crataegus oxyacantha and Eschscholtzia californica) in mild-to-moderate anxiety disorders . Curr Med Res Opin 2004)

~ A large single dose of Californian poppy (6.7 grams of herb - about 2 heaped tsps) was shown to cause a distinctive change in electroencephalograph recording (EEG) compared to readings obtained by placebo. (Schultz H, Jobert M, Hubner WD: Phytomed 5(6):449-458, 1998)

Some further pharmacological (laboratory) research includes

~ A sedative effect was observed for Californian poppy extract after injection and from high oral doses in experimental models in terms of both behavioural effects and promotion of sleep. The sedative and anxiolytic (anxiety reducing) are most likely linked to benzodiazepine-receptor activation because they were antagonised (blocked) by the benzodiazepine-receptor antagonist flumazenil in vivo (by injection).

~ Californian poppy extract inhibits the enzymatic degradation of catecholamines and the synthesis of epinephrine (adrenaline) in vitro. Preserving high levels of catecholamines may explain the sedative and antidepressant activity of Californian poppy.

~ An extract of Californian poppy (80%) and Corydalis (20%) has demonstrated the ability to interact with opiate receptors in vitro, which may explain its analgesic activity

Safety of Californian poppy

Californian poppy has not been found to have any adverse reactions in the medical literature. Although it is suggested to use it with caution in children with pain it should be noted that it has traditionally been used as a sedative and pain-reliever for the very young. Californian poppy is not seen to be a risk for pregnant or breastfeeding women (a good indicator that it is understood to be a highly safe herb).

As with all analgesics (pain relieving medicines) there must be a caution for overuse when the cause of the problem is not being addressed - paradoxically this can especially be an issue when a medication is working effectively! As the person has less pain they may be able to do more of that activity that was doing them harm and so potentially, in the long run, get worse rather than better.

General safety note on herbs

Therapeutic substances, and this certainly all includes all medicinal herbs, can do good and, therefore, also have the potential to do harm. The maxim that 'the poison is in the dose' precisely describes how too much of anything can be bad for us and the ancient rule to 'firstly, do no harm is, to this day, held as the core directive by all practitioners of traditional herbal medicine. So, not only are we careful to do our best to use the right herbs but, equally, we take care to not give too much of them or use them overlong.

For some years now, against this old, proven and safe way of herbalism, there has been a rising tide of excessive caution and scare-mongering in many parts of the world. The same authorities and medical publications that no so long ago decried herbal medicines as ineffectual have now taken up a different kind of adversarial position. That they are dangerous substances that should not be taken for a long list of reasons and really should only be prescribed by Doctors, who of course have zero training in them.

Lists of '10 popular herbs and why you should avoid them' include things like Garlic and Ginger that might 'thin your blood'. It is absurd to the point of the ridiculous, but fear is a universal driver, and fear has also been long proven to be effective when used to manipulate and control others.

I realise that the reader who comes to a page like this is unlikely to be swayed by such misinformation, but I nevertheless want to remind you that the reason that herbs cannot be patented or owned by any individual or corporation is that they are the people's medicine. They belong to us all and it is my great hope that you will learn how to use them safely and wisely for yourself and the people you care for. Be safe but do not be afraid.


Personal experiences

I have particularly warm feelings for Californian poppy, for over 20 years now, a picture of a beautiful field of its flowers has been on the front of my business card. This choice was no accident, the Poppy flower is a time-honoured symbol for every physician's wish, that all beings may be free from suffering and pain and the causes of suffering and pain.

Californian poppy is a medicine that I especially rate for those cases where pain and nervous tension have simply become too much for the person to manage without help.

I am especially fond of using Californian poppy in the form of a tea where using between 1-2 heaped tsps in a cup of hot water for about 10-15 minutes has a wonderfully relaxing action that can be felt throughout the entire nervous system.

The tincture of Californian poppy is also very good and can be most suited to situations when the medicine needs to be taken over a longer time frame. Dosage is always critical to get right in herbal medicine and here we have the challenge that for some people a smaller dose will work better than a larger one and for others it will be vice versa.

If in doubt, go somewhere in the middle of about 2-3 mls, but I would be ready to use less than that, just 1-2mls, or 20-40 drops, and likewise ready to go much higher than that, even up to 8 mls in a dose.

The best dose is the amount that the person can palpably feel relaxing them and making them feel more comfortable. More is not better once you get to that point, and it may in fact be less helpful.

It is not a drug-like, pain-blocking action we are getting from this poppy, it is very different to its opioid cousin the proof of which is that you may be assured that, given its abundance in the wild, that if habitual opioid addicts could get high from it, they certainly would, but they don't. Its action is more subtle, more gentle.

If the pain is bad and the need was great then I would start using a modest dose, a tsp of the dried herb, 3 or 4mls of the tincture, encouraging the person to feel its relaxing action and to wait for a good 1-2 hours to assess if it was making an obvious difference. Then take it again, less or more.

People are very ready to work with a medicine in this way. They want to feel better and understand that there is an optimal level that will not be too little or too strong. Too little and nothing much happens except a sense of worry that it won't be able to help. A too high dose has been reported to make people feel too sedated, too heavy and cumbersome. Again, the best dose is the amount that the person can palpably feel relaxing them and making them feel more comfortable.

Anyone that is studying herbal medicine or would just like to learn more about this great plant ally for their own reasons will do well to take a tsp of its tincture or a cup of its tea and then feel for themselves how gently and deeply the soothing, relaxing effects of Californian poppy go. This is part of what is described as the herbs 'action' and it is a marvellous way to deepen one's understanding - through experience.

As a herb to help with disturbed sleep, it is excellent to combine with the great pair of Passionflower and Skullcap. For children who are in discomfort or who likewise are having troubles sleeping I would likely use it with the gentle nerve tonics of Oatstraw and Chamomile

Pain Formula

Californian poppy 180mls
St John's wort 120mls
Skullcap 80mls
Passionflower 80mls
Licorice root 60mls
Peppermint 40mls

This would make 560mls, which would just fit into a 500ml amber pharm round. Bearing in mind that we make our own tinctures from organic dried material, so a different preparation from a different company or practitioner might need more or less for an equivalent dose. I would use anything from 4mls up to 10mls of this mixture, or one like it, for severe or chronic pain.

Frequency is just about as important as finding the right dose. Generally you will encourage a person to use it quite freely at first, every 3 or 4 hours, i.e. 4 or 5 times a day and then, once things have improved, to reduce the dose, or the frequency, as they wish. People don't want to have to take a lot of medicine, once they are feeling better they will naturally drop it to 3, then 2 times, then just once a day. The best sign of success is that they then simply forget to use it! Californian poppy is not addictive or habit forming. They will have no trouble to stop using it when they don't need it.


Constitutional note

Much of the information here about the traditional uses of Californian poppy is consistent with the model of thinking whereby one may treat problem A with plant B. There is value in this approach, especially in how it helps us pass on useful knowledge to one another, but it falls short in one vital area; and that is that people are not all cut from the same cloth! Something that works brilliantly for one person may do less for another -- why is this?

Part of the reason is that people vary in their constitutions as to whether they are either hotter or cooler and, at the same time, either dryer or damper. This useful and rather fascinating subject is introduced further here

Another big part of using the right herb when it is most needed comes from understanding the need to treat what is going wrong for the person that had led up to their getting a health condition. In this light, Californian poppy can particularly offer its benefits when a relaxing action is needed in the 'cycle of healing' , more about this here
