    I have been taking 10 drops of Crategus mother tincture for at least 2 years for blood pressure but am still suffering with readings anywhere from 205/107 to 244
    Is Crategus the same as Hawthorn. If so what dosage could/should I be taking?

    • DrSarahBrewer Post author

      Hi Stewart. You need to see your doctor as soon as possible as you need medication to control your blood pressure and to have your kidney function checked. Hawthorn (crataegus oxyacantha) alone is not enough (and should not be combined with prescribed medicines except under medical supervision) The term ‘mother tincture’ is usually applied to homeopathic remedies, which contain low levels of active ingredients (from which homepathic remedies are prepared by further extensive dilution), rather than herbal medicines which contain significantly higher levels of active ingredients. There are lots of natural remedies that can help lower a high blood pressure, and which you can use alongside medicines, such as relaxation exercises, breathing exercises, the DASH diet, magnesium supplements and ubiquinol coenzyme Q10, but you do need medical support with those readings.

    Hello, Are there supplements that contain Garlic, Magnesium and Hawthorne all in one ? (and potent enough to be effective) My BP is normally around 145/90 and I think the fact that I’m pretty high strung may not help me.

    • DrSarahBrewer Post author

      Hi Lawrence, There is a supplement called Advanced Blood Pressure Support which include a variety of effective herbs and nutrients, but not magnesium. As magnesium is easily obtained on its own, you could add that in if needed. If your blood pressure remains raised it’s important to see your doctor. Following a DASH diet is also key. You may find relaxation exercises and breathing exercises beneficial, too. And here’s a link to 45 natural remedies for lowering blood pressure. Best wishes, Sarah B

        I looked at that one but thought the Hawthorne and Garlic was too low. I thought I had read that you wanted over 1000 mg of hawthorne daily ?

      • DrSarahBrewer Post author

        When taking a combination of herbs and other ingredients which work in different ways you can use much lower doses to achieve a synergistic effect. These lower doses also reduce the risk of unwanted side effects. Hawthorn on its own is used in doses of 500mg to 1200mg per day but I believe these doses are best used under the supervision of a medical herbalist – it is a powerful herb. A lower dose in a combination supplement is a good way to start. Best wishes, Sarah B

    Hi— Seems that there are many supplements/herbs that can assist with lowering BP–you list quite a number of them on your very helpful website. There are dozens of different BP formulas on Amazon–hard to know where to start.

    Background–I am 59, developed hypertension 3 years ago-despite very regular exercise (5-6 days/week), regular meditation, a clean diet, and being thin (it runs in my family). Had a bad reaction to amlodipine, as well as a diuretic (and no impact on bp) –but bp lowered quickly with Lisiniprol. Shifted to Losartan after developing the dry cough. Have been maintained on 50/day, but now am having some side effects and would love to be able to lower the dose. However, even a minor reduction results in my bp increasing. My health is otherwise great.

    Do you have a recommendation of specific supplements or formulas that might be a support in allowing me to reduce the dose of Losartan successfully? Need to start somewhere–but there are so many options.

    thank you!!! Harry

      Hi Harry, Glad you found the site! Sounds as if you are already cutting back on salt and following a dash style diet which are key. I have listed the most effective natural remedies in a post on natural remedies for high blood pressure; magnesium is often deficient in diets and may help. Co-enzyme Q10 (ubiquinol form) is prescribed in Japan for hypertension. I’m also impressed with the Dr Tobias Blood Pressure formula. Different approaches work for different people, depending on the genes you have inherited, so there are no guarantees. Do check with your doctor before starting supplements. Best wishes, Sarah B

    Hello, thank you very much for all the precious informations that you share on your website.
    My question is: do you know if Klamath blue green algae (Aphanizomenon flos-aquae) is as good as Spirulina to reduce blood pressure?
    Than you for your help. Best regards

    • DrSarahBrewer Post author

      Hi Stephanie, Klamath blue green algae do not appear to have been specifically researched in relation to blood pressure, although they are likely to have similar effects as spirulina according to at least one review. However, there are concerns about levels of pollution in Lake Klamath which might contaminate supplements. Best wishes, Sarah B

      Hi Susan, Do go back to your doctor. You may need to change to a different class of antihypertensive drug, or have another one added in. Most people need 2 and sometimes 3 different medications to control their high bood pressure (often combined in one pill so you are not rattling). It’s important to bring your blood pressure down to target levels. In addition, natural approaches can help your medication to work more effectively. For example, lack of magnesium can reduce the effectiveness of some BP drugs, and correcting this will help you respond better. In the meantime, there are 45 different ‘natural’ ways to reduce blood pressure at this link. Click through on the ones that you would like to try for more details. Posts on the home page provide information too. Hope that helps, Best wishes, Sarah B

    Hi, I have three questions.

    I am taking Ramipril (2.5mg) before bed and Amlodipine (5mg) in the morning for my high blood pressure. I would like to also use Magnesium Bisglycinate and Apple Cider vinegar at meal times as my BP seems to go up, especially in the early evening. I have tried to check for interactions and have read the drug leaflets but can’t see any. I suppose, I am asking for clarification.

    I understand that high potassium from diet could interact with Ramipril, but what is a high potassium diet?

    I would prefer to use natural remedies to relieve or possibly eliminate my high blood pressure. I have started having cold hands and feet and poor libido, which after a year of taking my tablets may be the side effects. I know everyone is different, but is this a common reaction when taking these drugs?

    • DrSarahBrewer Post author

      Hi Roger, magnesium deficiency is common, and adding magnesium supplements to correct this can significantly improve blood pressure that has not previously responded to medication. Depending on how well your blood pressure is controlled, you may wish to start with a low dose and work up. The DASH diet will provide a good amount of magnesium from green leaves, nuts, seeds, fish, beans and wholefoods so you may wish to try this nutritional approach instead. The DASH diet is relatively high in potassium from fruit and veg, but is medically recommended for hypertension. Poor peripheral circulation and loss of libido can result from antihypertensive drugs, and amlodipine is often cited. Do see your doctor to ask if other classes of blood pressure medication might suit you better, control your blood pressure more effectively and not affect your libido. Don’t feel embarassed – GPs deal with this problem regularly. Hope that helps, Sarah B

    Hello – the article on red reishi is interesting. I take 32mg of Candesartan each morning, which I assume isn’t an immunosuppressive / anticoagulants or cholesterol-lowering medication, so would I be okay to take red reishi as well? I have got my BP down from the high 170s (at times it was in the 190s!) to mid 140s but am still trying to get it in to the 130s, and doing lots of intense exercise, avoiding all caffeine and alcohol and doing my best to avoid salt, but despite all these efforts, still can’t get it any lower hence my interest in red reishi.

    • DrSarahBrewer Post author

      Hi JB, I’ve checked with the Natural Medicines interaction database and it says: “Theoretically, concurrent use of reishi mushroom with antihypertensive drugs might increase the risk of hypotension.” Having said that, any oral supplement that lowers BP would have the same flag. If you do decide to take reishi – or any other natural approach – it’s important to monitor your blood pressure closely initially, and if taking a supplement, start with a low dose. I’ve just written an overview of all the blood pressure lowering natural remedies HERE. Hope that helps – it includes 39 possible approaches and the evidence behind them. Best wishes, Sarah B

    Is it true that while blood pressure treatments lower hypertension, they also kill the liver slowly, among other side effects.

    • DrSarahBrewer Post author

      Hi Arnie, most antihypertensive medicines don’t have adverse effects on the liver, but if you are concerned your doctor can check your liver function for you. The Patient Information Leaflet provided with each medicine will list possible side effects. Best wishes, Sarah B
