Mortar and pestle with 5 dried herbs that treat pollen allergies

Runny nose, clogged airways, tears, itchiness, rashes, cough… Pollen allergies, or pollinosis, turn spring into a dreaded dreary season for many of us. Some people who suffer from allergy even reach the point where going out isn’t an option anymore! Here is a selection of five plants that will help soothe and reduce bouts of pollen allergy.

1. Tarragon, the most effective pollen allergy regulator

Tarragon is a plant that is particularly effective against allergies. This plants contains compounds like coumarin and flavones that can extend the time between consecutive allergy inflammations. It’s very often recommended to reduce allergy-induced sinusitis, as it is to sooth skin rashes and itching. Tarragon essential oil displays powerful antihistaminic activity, mostly thanks to the concentrated methyl chavicol it contains.

Pregnant and nursing women, and babies and children younger than 3 years old, should not use tarragon essential oil. You must also refrain from using it if you’re already taking anti-coagulant medication.

2. Stinging nettle, a potent antihistaminic

Apart from its diuretic and purging properties, nettle also has some value as an antihistaminic agent. As soon as the first allergic symptoms appear, this plants helps counter allergy-induced sinusitis, by slowing the flow of mucus out of the nose. In addition, nettle contains high levels of vitamin C, which helps the body absorb quercetin and, as a consequence, reduces hay fever symptoms.

Pregnant and nursing women, and children younger than 12 years old, should not ingest nettle. This plant is also contra-indicated in case of edema and prostate cancer.

3. Thyme, a natural expectorant

Thyme helps decongest airways which is interesting to alleviate suffering related to hay fever.

In a bowl of hot water, pour a single drop of thyme essential oil.


Thyme should not be used if you’re allergic to plants of the Lamiaceae family. It’s also not recommended for persons who suffer from hypertension or who are taking anti-coagulant medicines.

5. Black currant, to reduce sensitivity to allergens

Black currant is an effective anti-inflammatory that succeeds in blocking the release of histamine, the molecule that triggers allergic reactions. On top of that, black currant contains high levels of manganese, a trace element that reinforces mucus linings in the breathing organs: healthy mucus linings reduces sensitivity to allergens. In this particular application, black currant bud extracts, much used in gemmotherapy, is a preferred solution to help people who suffer from chronic allergies.


Black currant buds can be macerated to produce a pollen allergy treatmentFor adults and teenagers, add 5 to 15 drops of macerated blackcurrant buds in a glass of water. Drink this every morning for 3 weeks. Best is to ingest it 15 minutes before breakfast, without skipping breakfast.

Macerated black currant buds not be used in any manner by children below the age of 3 nor by pregnant and nursing women. Persons suffering from heart or kidney failure should consult a doctor before taking any black currant berry or leaf supplements.
