A Simple Alternative to Antihistamines

Last updated on November 1st, 2022 at 04:58 pm

Does your favorite rose bush leave you sneezing, or a bug bite cause an itchy welt on your arm? Chances are you’ve popped a little pink antihistamine pill looking for help. Antihistamines block the body’s histamine receptors. Histamine is a substance released by cells when something harmful is detected like an allergen such as a flower’s pollen or the sting of an insect. These drugs provide some relief, but your symptoms will come roaring back once they’ve worn off. They also come with that one big drawback you know all too well — excessive sleepiness — because they inhibit other essential functions that histamine has in your body.

Fortunately, homeopathy has a simple answer for those suffering from allergies. Histaminum hydrochloricum is a versatile remedy that works for a range of allergic conditions.

How Histamine Works

Histamine is present in the cells and tissues throughout your body, and it’s also naturally occurring in the venom of wasps, bees, and jellyfish. People with allergies may view histamine as the enemy, but it serves a necessary purpose.

On a basic level, histamine helps protect the body and get rid of things that bother you. For instance, histamine gets released during injuries and infections. It works to increase blood flow in the affected area for the benefit of healing. It’s this blood flow effect (vasodilation) that unfortunately causes you to itch, sneeze, or tear up in response to an allergen, which your body perceives as a threat and attacks. As a neurotransmitter, histamine also sends signals to your stomach to produce acid and to your brain to keep you alert, which is the reason antihistamines can leave you feeling sluggish.

Issues arise when histamine levels are excessive, as is the case with allergic conditions. In these situations, harmless substances like food or pollen can set off rapid production of more histamine. As you continue to encounter these triggers, histamine production stays high and leads to those well-known and annoying reactions in our eyes, nose, and skin.

Histaminum Hydrochloricum for Allergies

Histaminum hydrochloricum is prepared from a salt of histamine called histamine dihydrochloride. Unlike antihistamines that block the body’s response, a microdose of histamine dihydrochloride can help your body regulate how much histamine it naturally makes. Therefore, you’ll get all the benefits of allergy relief without feeling drowsy.

This “blue tube” medicine is so versatile that you’ll want to keep it always stocked in your first aid kit. It relieves symptoms of allergic conditions, including hay fever.* You can find it as an active ingredient in RhinAllergy for this purpose. It’s also a useful remedy for hives and reactions to insect stings.*

For general use throughout allergy season and beyond, dissolve 5 pellets of Histaminum hydrochloricum 30C under the tongue three times a day until symptoms are relieved. When treating hives and other skin reactions, use 5 pellets every hour, then decrease the frequency as your symptoms improve.

I experienced prolonged effects from the first two vaccines like fatigue, nausea, headaches…. and for the first two days, flu like symptoms. I found that Arnica and Hypericum helped with the body aches with the first two vaccines. The side effects from the second jab was worse than the first. I’m due to get the Booster jab next week and thought I might try to alleviate the side effects. Thanks

    1. Thank you for your question, Karen. At this point, not much is known about the effect of the COVID-19 vaccine on medications and vice versa. For information about specific drug use and the vaccine, check with your health care provider.

  13. Hi, my 17 year old had been coming up with Urticaria type skin rash for last 4-5 months. Have ruled out food groups but still cannot really figure out what the problem is. He has been taking antihistamines and steroidal creams to releive the itchiness.
    Will Histaminum help?
    Could this sudden occurrence of urticaria be because of hormones at this age. Has anyone had this experience with their teenagers?

    1. Hi Vandy, if the rash is caused by an allergy, then Histaminum is indicated. Urtica urens is another popular remedy for allergic skin reactions. However, these medicines are only for over-the-counter use for up to three days. If you wish to use them for longer, we recommend reaching out to a homeopathic practitioner who can prescribe a treatment regimen tailored to your teen. Find one in your area by contacting the National Center for Homeopathy at info@homeopathycenter.org or visit http://www.homeopathycenter.org.

    2. Yes, my first time breaking out with random hives I was 16 and I am now 44 and still have them. They come when my body gets too hot. I was told by a doctor the nerves can be triggered by a crises in your life. At the time that made since. Why I still suffer from them I don’t know. I have no food allergies or anything. It’s horrible they break out and itch so bad. I’ve been on Claritin and Zyrtec for years to keep it away. It helps, but I’m afraid I am having side effects of those meds now that I’ve been on them so long. That’s why I’m looking into this now.

    1. Hello Nishi, Rhus tox and Bryonia are two main homeopathic medicines for joint pain. Use Rhus tox if moving helps improve your knee pain, or choose Bryonia if your knee is better when rested. You will find both medicines in our Arnicare Arthritis formula, which is easy to use and address multiple symptoms of joint pain.

  14. Dear all,
    I have tried Histaminum 30ch and 200ch for trying to get relieve for the moments where my histamine levels are over the expected and, due to my *histamine intolerance* ground, affects to my sleeping a lot.
    I know that “every patient a different treatment” BUT, is there a way to counteract or nullify the histamine levels in blood given that Histaminum 30ch or 200ch does not give relief in my case ? (only affects to sleep)
    thanks! 😉

    1. Hi Pedro, it would be best to speak to a practitioner knowledgeable in homeopathy about your condition.

  15. Redness in face and almost a sunburn feeling- can this be a side effect after taking the Histaminum pellets?

    1. Hello Jenna, as a manufacturer, we offer over-the-counter medicines for acute, self-limiting conditions. However, health care professionals may instruct their patients to use the medicine for other conditions. Homeopathic treatments for chronic conditions like Mast Cell Activation Syndrome are very specific to each patient.

  16. I take Singular and want to stop. I have tree and grass pollen allergies., but I am also lethargic all summer into fall. Can you recommend something? I use Arnica for arthritis and like it a lot. Allergy season is starting and I need help. Thank you

    1. Hi Linda, we recommend non-drowsy RhinAllergy medicine. It relieves symptoms of hay fever and other respiratory allergies, including itchy and watery eyes, runny nose, and spasmodic coughing in easy-to-use meltaway tablets, no water needed. Singular is a prescription medication, so please speak to your doctor before stopping it. RhinAllergy has no known drug interactions, so it’s safe to take with Singular or other medications you may already be using.

    1. Hi Richard, homeopathic medicines are available in various dilutions, but C, X, and CK are the most common. The letter indicates which dilution process was chosen, while the number indicates how many times that dilution process was used, and consequently, which symptoms the medicine is meant to treat. You can read more about that here on this page.

      Low dilutions, such as 6X or 6C, will relieve local symptoms such as those can point a finger at (e.g., an insect bite or bruise). High dilutions, such as 30X or 30C, will relieve general symptoms, which is more than one symptom in more than one location with possible behavioral or emotional symptoms (e.g., a very high fever and chills, accompanied by agitation or sleeplessness). If a person has the right medicine, no matter what the dilution, he will see a lessening of symptoms.

  18. I have horrible congestion and have been trying to make sure that the Histaminum Hydrochloricum or sinucalm won’t raise my blood pressure, I am on blood pressure medication and know they can be taken together but will it raise blood pressure ? Thank you

    1. Hi Courtney, homeopathic medicines will not raise your blood pressure or interact with blood pressure medication. SinusCalm and Histaminum do not contain conventional decongestants (like phenylephrine), which are the ingredients responsible for increasing blood pressure and heart rate in allopathic over-the-counter sinus and allergy medicines.

  19. I may have mast cell activation syndrome blood test shows allergies of ragweed, pollen, cedar, dust mites.. Will Histaminum hydrochloricum help

    1. Hi Puja, Histaminum relieves symptoms of all allergic conditions, including indoor/outdoor and seasonal allergies, as well as hives. However, we do recommend consulting a homeopathic practitioner who can provide you with an individualized treatment plan.

    1. Hi Tim, Histaminum is not contraindicated with your condition, but be sure to consult with your healthcare provider regarding OTC medications including homeopathics. Thanks!

    1. Kelly Olsen-Stanko

      Hi Dierdre, there are no known drug interactions between Zyrtec and Histaminum. Homeopathic medicines in general are safe to take with conventional medications and even herbs or supplements without the risk of interacting.

  22. Can this product be taken along with standard, over the counter medicine such as Zyrtec? This product alone isn’t relieving all of my symptoms in the Spring. Thank you.

    1. Hello Sheila, there are no known drug interactions between Zyrtec and Histaminum. Homeopathic medicines in general are safe to take with other medications or supplements without the risk of interacting.

  23. Hi. Can I take Histaminum hydrochloricum 30C as a daily preventive during allergy season? I started taking 5 pellets, 3 times a day when my allergy symptoms started. It was a great relief but I fear that they will return if I stop usage. Can I continue taking a daily dosage?

    1. Hello Val, the duration of use is listed on the product label. For Histaminum, the length of use is 3 days. We recommend that you consult with your health care professional on any medicine that you intend to take for a longer period of time. Thanks!

  24. Hi. I’ve been dealing with an allergic reaction (to what, I don’t know) that makes my tongue and lips hurt and slightly swollen. It has happened a few times over the past few years and on two occasions it was bad enough that I took Benadryl, which got rid of it after using it for a week. However, I am 72 years old and Benadryl is hard on me. My body responds with fibromyalgia symptoms, including bad headaches and vertigo. Recently I learned of Histaminum Hydrochloricum and tried it with some success about 10 days ago. Then, a week later the tongue and lip symptoms came back, so I am once again taking doses of the HH. This time it is apparently not working, or hasn’t after two days. I noticed on your website that skin reactions can be treated with 5 pellets every hour until symptoms lessen. Does that seem like something I could do with with this allergic reaction? Anything else you can recommend? Thank you!

    1. Hi Jennifer, we recommend getting immediate emergency help if you experience hives along with swelling in or around your mouth. We like to know more about your experience. Can you please call us at 1-800-264-7661? Thank you.
