Grey alder (Alnus incana) is a large shrub or tree in the birch family. It grows in the European part of Russia, the Urals, the Caucasus and Siberia. For medicinal purposes, its fruiting bodies are harvested, commonly called alder cones. However, the traditional use of plant materials does not mean that every homemade infusion is safe or suitable for self-treatment.

## How to Identify Grey Alder in the Wild

Grey alder belongs to the birch family (Betulaceae). It grows as a tall shrub or tree and can reach 20 meters in height. It is easy to recognize by the combination of its light-colored bark, distinctive leaves and small fruiting bodies.

The bark of grey alder is smooth and light gray. Its leaves grow alternately along the branches and have stalks. They are ovate or oval-elliptical in shape. The leaf tips are pointed, and the edges are doubly serrated.

Young leaves are densely covered with hairs. As the leaves mature, their upper surfaces become smoother or retain closely appressed hairs. The undersides have a bluish-gray tint. They may be almost hairless or slightly hairy. The hairs are more noticeable along the veins and sometimes form a grayish, felt-like covering.

Grey alder flowers in early spring, before the leaves appear. Its flowers grow in catkins. Male and female flowers occur in separate inflorescences. As the fruits mature, the scales of the female catkins enlarge and become woody. This produces small fruiting bodies that resemble tiny cones.

These fruiting bodies are the part used as medicinal plant material. They are different from young catkins and individual seeds. Therefore, when harvesting, it is important to identify the plant correctly and collect the appropriate part.

## Where Does Grey Alder Grow?

Grey alder is widespread in the central and northern parts of the European territories of the former USSR, the Urals, the Caucasus and Siberia. Botanical descriptions list various habitats, including forest edges, woodland margins, clearings and burned areas.

The plant is found along streams and rivers. It grows in damp meadows and in the understory of forests with moist soil. In Perm Oblast, grey alder is described as a widespread plant found near rivers, lakes and marshes, as well as in damp forests.

Grey alder and black alder, also known as common alder (Alnus glutinosa), belong to the same genus. However, they are different species. Pharmacognosy reference books indicate that the fruiting bodies of both species are permitted for medicinal use.

When harvesting the plant yourself, it is important not to rely solely on its habitat. Grey alder and other species may grow under similar conditions. To identify the plant, consider the bark color, leaf shape, leaf hairs and the structure of the fruiting bodies.

## What Are the Benefits of Grey Alder Fruiting Bodies?

The main medicinal plant material obtained from grey alder is its fruiting bodies, which reference books call alder cones. They form after the fruits mature, when the scales of the female catkins become hard and woody.

According to pharmacognosy literature, grey alder fruiting bodies are harvested for medicinal purposes. This confirms their use as plant material. However, the fact that a plant appears on lists of medicinal species does not establish the effectiveness of a particular homemade remedy.

Grey alder, whose benefits interest readers of herbal medicine articles, requires careful consideration when selecting plant material. Recipes involving the leaves, buds or other parts of black alder cannot automatically be applied to grey alder. Preparations made from different alder species should not be considered equivalent, either.

### What Is Alder Used for in Herbal Medicine?

Older herbal books describe ways of using various plants, including alder. However, the recipes may refer to a different species or combine several ingredients. For example, reference literature includes descriptions of water-based decoctions containing black alder fruiting bodies and other plants.

Such information does not justify using the same recipe for grey alder. It is important to know the exact plant species, the part used and the proportions specified in the particular recipe.

Grey alder, when considered as a source of medicinal plant material, should not be used as a substitute for medical care. You should not choose a plant to treat symptoms on your own without first determining their cause.

When evaluating any herbal remedy, you need to consider not only its source but also how it is prepared, the amount of plant material used and the person's health. A recipe from an old herbal book does not, by itself, establish that it is safe in every situation.

## How Is Grey Alder Used?

Grey alder fruiting bodies are used for medicinal purposes. They are harvested as a distinct type of plant material. However, information about harvesting does not mean that there is a universal recipe for an infusion or decoction suitable for self-treatment.

Older literature contains recipes for water-based decoctions that include alder. Some of these descriptions, however, refer to black alder or mixtures of several plants. The proportions given in such recipes should not be applied to Alnus incana without confirmation that they are appropriate.

When choosing a ready-made preparation, check the plant's name and the ingredients. Also make sure that the instructions specify the intended method of use. Plant material of unknown origin and products without clear labeling are not suitable for self-treatment.

An infusion, a decoction, an alcohol tincture and a concentrated extract are different forms of herbal preparations. They cannot be treated as interchangeable. Their composition and concentration may vary, so the instructions for one product should not automatically be applied to another.

### Grey Alder: Can You Brew It Yourself?

To prepare an infusion at home, you need a verified recipe specifically intended for grey alder. You should not arbitrarily decide how much plant material or water to use, how long to steep it or what the daily dose should be.

Medicinal plant reference books describe alder fruiting bodies as plant material, but this is not enough to establish a safe home-use regimen. Recipes intended for black alder should not automatically be used for Alnus incana.

If a specialist recommends an alder-based preparation, clarify a few points:

- Which plant species is listed in the ingredients?
- Which part of the plant is used?
- Is the preparation intended to be taken by mouth?
- What dosage is specified in the instructions?
- Which contraindications should be considered in light of your health and any medications you take?

Choose products with clearly listed ingredients and straightforward instructions. If the plant species or method of use is not specified, it is safer to avoid using the product until you have clarified the information.

Do not increase the amount of plant material in the hope of making the infusion more effective. A higher concentration does not guarantee greater benefits and may increase the risk of unwanted reactions.

## How to Harvest and Store Alder Cones Properly

Grey alder fruiting bodies are harvested for medicinal purposes. This is the part of the plant identified in reference books as medicinal plant material. Leaves, bark and buds should not automatically be used in place of the fruiting bodies.

The first step in harvesting is to identify the plant correctly. Grey alder grows along rivers and streams, in damp meadows, in the understory of moist forests, and along woodland edges and clearings. However, its habitat alone is not enough to identify the species with certainty.

Inspect the fruiting bodies before harvesting. Do not collect material showing visible signs of mold, rot or damage. Material of unknown origin, or material from a plant whose species cannot be confidently identified, is also unsuitable.

After harvesting, prepare and dry the fruiting bodies according to the guidelines for the relevant medicinal plant material. Avoid dampness and spoilage. The exact processing conditions should meet the requirements for that particular type of material.

Store dried fruiting bodies in a dry place, protecting them from moisture. For convenience, you can label the container with the plant's name and the harvest date. Inspect the material periodically. If mold, a musty smell or noticeable changes in appearance develop, do not use it.

Avoid harvesting large quantities of the plant if you do not have suitable storage conditions. Improper storage can reduce the quality of the material. Fruiting bodies that look intact do not necessarily retain their original properties.

If you have no experience identifying plants or harvesting medicinal plant material, it is more sensible to choose ready-made products that clearly identify the plant species and provide straightforward instructions. This helps prevent mistakes during collection and identification.

## How to Find Grey Alder Abroad

Outside Russia, grey alder is easiest to search for by its Latin name, *Alnus incana*. Common names may also refer to other alder species, so check the product ingredients.

**What the plant is called:**
- USA: grey alder or gray alder; also found under the names speckled alder, thinleaf alder and white alder.
- Germany: Grau-Erle or Grauerle.
- France: aulne blanc, aulne gris or aulne des montagnes.
- Latin name: *Alnus incana*.

**Forms in which it is sold:**

A macerate made from fresh buds and young shoots is more commonly found as a liquid in a dropper bottle. In France, you may also find gemmotherapy preparations and homeopathic products made from buds or young plant tissues. Dry plant material, tea bags and capsules containing this particular alder species are rarely documented on the market.

**Where to look:**
- USA — specialty herbal shops, online stores selling plant materials and some health food stores.
- Germany — pharmacies (Apotheke), herbal shops, Reformhaus stores and online pharmacies.
- France — pharmacies, parapharmacies, gemmotherapy suppliers and herbal shops.

**What to check on the packaging:**
- The Latin name *Alnus incana* and the part of the plant used.
- The preparation's form, country of origin, extract ingredients and alcohol content.
- The batch number, dosage and organic certification, if claimed.

Do not confuse grey alder with *Alnus glutinosa* or North American alder species.

In the USA, dietary supplements do not undergo FDA premarket approval for safety and effectiveness. In Germany, Arzneitee (medicinal herbal tea) is classified as a medicinal product and is subject to the relevant pharmaceutical requirements.

## Grey Alder: Contraindications and Precautions

Modern safety data for oral use of Alnus incana are limited. No specialized monographs from EMA, NIH/NCCIH, Drugs.com or Memorial Sloan Kettering specifically describing the clinical safety of grey alder as an oral herbal preparation have been identified. Therefore, the lack of detailed information about adverse reactions should not be taken as proof of safety.

**Allergies.** People with a known allergy to alder pollen should exercise caution. Alder pollen can cause allergic rhinitis. Symptoms may include sneezing, a runny nose, itching and other signs of an allergic reaction. If symptoms develop after contact with the plant, stop contact and assess the severity of the reaction.

**Pregnancy and breastfeeding.** The safety of medicinal doses of grey alder during these periods has not been established. There is insufficient information about possible effects on the fetus or a breastfed infant. Therefore, do not take oral preparations without consulting your doctor.

**Children.** Reliable data on the effectiveness and safety of grey alder preparations in children are limited. Do not select a dosage or use concentrated herbal preparations on your own. Discuss the possibility of use with a pediatrician.

**Drug interactions.** Clinically confirmed interactions specific to Alnus incana have not been established. This does not mean that interactions are impossible. If you take medications regularly, consult your doctor or pharmacist before using herbal preparations.

**Adverse reactions.** There is insufficient information about the frequency and nature of adverse reactions associated with oral use of grey alder. Allergic reactions and gastrointestinal disturbances are possible. Additional risks arise from misidentifying the plant, contamination of the raw material and unpredictable concentrations of substances in homemade preparations.

**Dosage and overdose.** A universally safe medicinal dose of grey alder for independent oral use has not been established. Do not ingest plant material of unknown origin or products without clear instructions. Natural origin does not guarantee that a preparation is safe.

If you experience difficulty breathing, facial swelling, severe vomiting, confusion or fainting after taking an herbal remedy, seek emergency medical attention.

## When to See a Doctor

You should see a doctor if symptoms recur, become more severe or interfere with your daily life. Herbal remedies should not delay medical evaluation or investigation into the cause of your symptoms.

If you have a chronic condition, discuss the use of any new preparations, including herbal products, with your healthcare professional. This is especially important if you take medications regularly. Your doctor can assess the possible risks and determine whether a particular product is necessary.

During pregnancy and breastfeeding, do not take grey alder preparations in medicinal doses without medical advice. Children also require an individual approach based on their age and health.

If you develop a runny nose, itching, a rash or other signs of an allergic reaction after contact with alder, stop contact with the suspected allergen. If you experience breathing difficulties or facial swelling, seek emergency medical care immediately.

Extra caution is needed when using plant material you have collected yourself. Misidentification, improper drying and contamination can make it unsuitable for use. Every medicinal plant requires careful handling. Before using it, make sure the species has been correctly identified, consider possible contraindications and seek medical advice if necessary.
