Herbal suggestions are:
Reishi mushrooms are super-powerful medicinal mushrooms that both stimulate the immune response and reduce the histamine production in the body. They are available in capsule form, which makes them easy to take, and are best taken two to three times a day.
Freeze-dried nettle is a green plant filled with chlorophyll that has been shown in clinical studies to be as effective as today’s allergy medicines. The positive side of taking nettles is that most people feel clearing in their nose, eyes and sinuses within 20 minutes, and nettles don’t have the side effects of most modern anti-allergy medicines, like sleepiness and dry mouth. The downside is that the effectiveness of nettles can wear off in four hours, so they need to be taken more often than conventional medicines. And while taking nettles can be likened to eating a wild salad, they also come in an easy-to-take capsule form.
Homeopathy is not taken preventatively, but can help alleviate symptoms at the first sign of allergy. It may take a little trial and error before one finds the correct homeopathic remedy that suits your specific symptoms, because homeopathic remedies target an individual’s reactions to a sickness rather than attacking the ailment directly, but the relief can be wonderful and worth the effort.
Some Homeopathic remedies choices are:
Allium Cepa 30c is used for constantly tearing eyes, sneezing and liquid that is coming out of the nose.
Sabadilla 30c is used for a stuffy nose that also drips, constant sneezing and dripping eyes. It’s also used when the allergy can be felt in the lungs.
Arundo 30c is used for that annoying scratching that can be felt in the back of the mouth by the soft palate, inside the nose and ears.
