Quick answer — three adaptogens to begin with

For anyone opening the subject for the first time: Ashwagandha (Withania somnifera) — an Ayurvedic root held sacred for 5,000 years, support for the nervous system and for sleep; Rhodiola rosea — a Siberian and Scandinavian root, support for mental and physical effort; Reishi (Ganoderma lucidum) — the Chinese lacquered mushroom, listed as a 'superior remedy' in the Shen Nong Ben Cao Jing (~200 CE).

The word 'adaptogen' itself dates to 1947. Coined by the Soviet pharmacologist Nikolai Lazarev to name a class of substances that raise the body's non-specific resistance to stress. Three criteria for a plant to be adaptogenic: non-toxic at normal doses, a normalising (rebalancing) action, a non-specific action (no single system targeted).

What is an adaptogen — a rigorous definition

The word 'adaptogen' is not a vague marketing term. It has a precise definition, formulated in 1947 by Nikolai Lazarev, widened in 1968 by his student Israel Brekhman and Igor Dardymov. Three criteria:

**1. Safety.** An adaptogenic plant must be non-toxic at traditional doses of use, over a prolonged period. No hepatic accumulation, no dependence, no marked adverse effects.

**2. Non-specific action.** It raises general resistance to stress (physical, chemical, biological, psychological) — not a single targeted axis. This is what distinguishes Ashwagandha (an adaptogen) from valerian (a specific sedative). Not better; different.

**3. Normalising action.** It rebalances — that is, it lowers what is high and lifts what is low. Cortisol high in the morning, cortisol low at night: an adaptogen works in both directions, not in just one.

This rigorous definition rules out many plants sold as 'adaptogens' in today's wellness market. Not all medicinal plants are adaptogens. Ginseng, yes. Dandelion, no. Chamomile, no. Tulsi, yes. A poor adaptogen = the wrong plant (chamomile tends to something else). A false adaptogen = bad marketing.

1. Ashwagandha — the strength of the horse

Withania somnifera. An Ayurvedic root held sacred for at least 5,000 years. The Sanskrit word *ashwa-gandha* means 'smell of the horse' — the fresh root gives off a characteristic animal scent. The name is also metaphorical: whoever takes the root receives the strength and vitality of a horse.

The Charaka Samhita (~1000 BCE) places Ashwagandha among the *rasayana* — the plants of longevity and regeneration. It is traditionally given to convalescents, to the elderly, and to women after childbirth.

Chemistry: withanolides (sitoindosides, withanolide A, D), alkaloids, saponins. The full cortège of the whole root works in synergy — and that is precisely why INFUSE refuses third-party standardised extracts and offers the whole root in powder.

Contemporary pharmacology documents: a measurable drop in salivary cortisol after 8 weeks (Chandrasekhar et al., 2012, Indian Journal of Psychological Medicine), improved deep sleep, thyroid support (at a moderate dose). 100+ clinical studies published since 2000.

Traditional vaidya preparation: 3–5 g of powdered root in 200 ml of warm milk (animal or plant), at night, for 6–8 weeks. The typical Ayurvedic course lasts 3 to 6 months, with a 1-month pause afterward.

INFUSE offers Ashwagandha as an organic root from India, in powder. Full article: **Ashwagandha — the strength of the horse**.

2. Shatavari — the queen of women's plants

Asparagus racemosus. An Ayurvedic root; the Sanskrit word *shata-vari* means 'she who has a hundred husbands' — a reference to its reputation as a plant of love, of fertility, of feminine abundance. The Charaka Samhita places it among the major feminine *rasayana*.

Ayurvedic pharmacopoeia: Shatavari is given to young girls at puberty, to women in a difficult menstrual cycle, to women in perimenopause, to nursing mothers (a documented galactagogue effect).

Chemistry: shatavarins (steroidal saponins), polysaccharides, mucilages, isoflavones. A gentle phyto-oestrogenic action, a modulation of oestrogen receptors according to endogenous levels — that is, it raises the oestrogenic effect in case of deficiency and lowers it in case of excess. A hormonal adaptogenic action in the strict sense.

Contemporary pharmacology: a confirmed galactagogue action (Sharma et al., 1996, Indian Journal of Medical Research), perimenopause support documented preliminarily. Active research on PCOS and endometriosis.

Traditional preparation: 3–5 g of powdered root in 200 ml of warm milk (ideally animal, for a traditional potentiation), in the morning or evening. A course of 3–6 months minimum.

Caution: women with a history of hormone-dependent cancer (breast, uterus, ovary) — consult beforehand. INFUSE offers Shatavari as an organic root from India. Full article: **Shatavari — queen of the rasayana**.

3. Rhodiola rosea — the golden root of Siberia

Rhodiola rosea. A small rupestrine plant of the Arctic mountains (Siberia, Scandinavia, Alaska). Known to the Vikings since the 9th century (the Edda Saga) and to Siberian shamans far longer. Soviet pharmacology studied it intensively from 1948 on, within the programme to support military performance.

The nickname 'golden root' comes from the gold-yellow colour of the fresh root when split, and the scent of rose it gives off (hence *rosea*).

Chemistry: salidroside, rosavins (rosin, rosarin, rosavin), tyrosol. The rosavins/salidroside ratio (ideally 3:1) is an ethnobotanical marker of quality. Documented action: modulation of serotonin, dopamine, noradrenaline; mitochondrial support; cellular protection against oxidative stress.

Contemporary pharmacology: improvement in mental and physical fatigue (Olsson et al., 2009, Planta Medica — a study of 60 subjects), reduction in burn-out symptoms (Kasper et al., 2017, Neuropsychiatric Disease and Treatment).

Traditional Siberian preparation: a decoction of dried root (5–10g per litre of water), drunk warm in the morning. Modern preparation: 100–300 mg of powder standardised to 3% rosavins + 1% salidroside, in the morning.

Caution: may disturb sleep if taken late in the day. INFUSE offers Rhodiola as a dried organic root sourced from Siberia or Scandinavia. Full article to come.

4. Maca — the food of the Andean plateau

Lepidium meyenii. An Andean brassica cultivated at 4,000m altitude in Peru and Bolivia for at least 2,000 years. Domesticated by the Chinchaycocha and Pumpush peoples before the Inca expansion. Mentioned by the Spanish chroniclers (Garcilaso de la Vega, ~1609) as a staple food and a plant of animal and human fertility.

Maca is one of the very few plants in the world that grows at this extreme altitude — it has developed a singular chemical cortège (macamides, glucosinolates, sterols) that pharmacology is only beginning to understand.

Three varieties according to the colour of the root: yellow (the mildest, for daily food use), red (feminine, fertility, energy), black (masculine, strength, deep sleep). This threefold distinction is a traditional Andean one, not recent marketing.

Contemporary pharmacology: improvement in male and female libido (Gonzales et al., 2002, Andrologia), fertility support, cortisol modulation, perimenopause support (Meissner et al., 2006).

Traditional Andean preparation: yellow Maca as flour, folded into daily food (flatbreads, soups, warm drinks). Typical dose: 5–10 g per day, in a 3-month course.

Caution: hyperthyroidism (Maca contains trace goitrogens — better to cook it). INFUSE offers yellow, red and black Maca from Peru. Full article: **Yellow Maca — food of the plateau**.

5. Reishi — the mushroom of immortality

Ganoderma lucidum. A brown-red lacquered mushroom, known in Chinese medicine for at least 4,000 years. The *Shen Nong Ben Cao Jing* (~200 CE) — the first Chinese treatise of materia medica — lists it as a 'superior remedy', the category reserved for substances that can be taken over the long term without side effects and that strengthen the *jing* (vital essence).

Reishi is also called *Lingzhi* in Mandarin — 'mushroom of long life'. Depicted in Taoist iconography since the 2nd century, often beside the immortals.

Chemistry: beta-glucans (1,3 and 1,6), triterpenes (ganoderic acids A to Z), peptides, ergosterols, polysaccharides. An immunomodulating and adaptogenic action documented by 200+ studies since 1990.

Contemporary pharmacology: modulation of the immune system, improved deep sleep, a hepatoprotective action (Wachtel-Galor et al., 2011, NCBI book chapter). Active research in complementary oncology (never in place of standard protocols).

Traditional preparation: a long decoction (2–4 hours) of dried sliced fruiting bodies. Double extraction (water + alcohol) is essential to release both the water-soluble polysaccharides and the fat-soluble triterpenes. A course of 3–6 months minimum.

INFUSE offers Reishi as a double-extracted powder. Full article: **Reishi — the mushroom of immortality**.

6. Cordyceps — the breath of the summits

Cordyceps militaris (cultivated) or Cordyceps sinensis (wild Tibetan). Parasitic in origin, it became the companion of Tibetan shepherds and Mongol nomads at least 1,500 years ago, for resistance to altitude.

Cordyceps entered Western awareness in 1993, when Chinese athletes shattered several world track records in Beijing. Their coach publicly attributed the performance to daily consumption of Cordyceps.

Chemistry: cordycepin, polysaccharides, mannitol (cordycepic acid), adenosine, ergosterols. Documented action: improvement in cellular ATP production, tissue oxygenation, mitochondrial support (Hirsch et al., 2017, Journal of Dietary Supplements).

An adaptogen specialised in supporting physical effort and oxygenation. Of particular interest to endurance athletes, people living at altitude, and those recovering after a respiratory illness.

Preparation: double extraction is mandatory to release the cordycepin and the polysaccharides. A course of 8–12 weeks, 2–3 g per day. Not to be taken at night (may disturb sleep in some people).

Caution: wild Tibetan Cordyceps sinensis is under major ecological pressure (intensive harvesting, exorbitant prices). INFUSE offers ethically cultivated Cordyceps militaris. Full article to come.

7. Schisandra — the berry of the five flavours

Schisandra chinensis. A vine of Northern Asia (China, Eastern Russia, Korea, Japan), its red berries in clusters. The Chinese name *Wu Wei Zi* — the berry of the five flavours — literally describes the taste: sweet, sour, bitter, salty, pungent. A single plant that holds the five flavour-elements of traditional Chinese medicine.

Schisandra is documented in the *Shen Nong Ben Cao Jing* (~200 CE) as a 'superior remedy'. Russian pharmacopoeia studied it intensively from 1940 on, within the research on Soviet military performance.

Chemistry: schisandrins (lignans A, B, C), gomisins, stigmasterols, vitamin E. A major hepatoprotective action (the schisandrins stimulate the production of phase II liver enzymes), adaptogenic, with improved concentration and memory.

Contemporary pharmacology: a confirmed hepatic protection (Panossian & Wikman, 2008, Phytomedicine), improvement in markers of chronic stress, cortisol modulation.

Traditional preparation: 1–3 g of dried berries in a daily infusion or decoction. The Chinese tradition chews them fresh. A course of 3–6 months.

Caution: gastro-oesophageal reflux is possible in sensitive people (the berry's natural acidity). INFUSE offers Schisandra as dried berries (to come in the catalogue). Full article to come.

How to choose according to your profile

You mostly carry chronic stress, light sleep, irritability. **Ashwagandha** + **Reishi** at night. The best-documented combination for lowering nocturnal cortisol and improving deep sleep. A course of 8–12 weeks.

You are a woman in a difficult cycle, in perimenopause, or wishing for fertility. **Shatavari** + **red Maca** + **Ashwagandha**. An Ayurvedic + Andean hormonal architecture, support for softness and for balance.

You mostly carry mental fatigue, cognitive fog, a hard start to the day. **Rhodiola** in the morning + **Schisandra** through the day. Neuro-cognitive support + hepatic protection.

You are an endurance athlete, you live at altitude, or you are recovering from a respiratory illness. **Cordyceps** in the morning + **Reishi** at night. Mitochondria + deep sleep.

You want a complete, multi-system adaptogenic support without having to manage several plants. **Adaptogenic Blend INFUSE** — a combination of Ashwagandha + Shatavari + Chaga + Mucuna + Maca + Lucuma. A course of 6–8 weeks, 30g/day in the morning.

Traditional combinations

**Chyawanprash** (Ayurveda, ~1000 BCE) — a jam of 50 herbs including Ashwagandha, Shatavari, Mucuna, Amla and many other rasayana. A teaspoon morning and evening, stirred into warm milk. A millennia-old tradition of daily support.

**Rasayana Lehyam of Kerala** — an Ayurvedic medicinal preparation of southern India, built on Ashwagandha + Shatavari + ghee + honey, taken for 6–8 weeks as a foundational course.

**The Chinese 'three treasures' tonic** (Jing-Qi-Shen) — a combination of Ginseng + Reishi + Schisandra. A Taoist tradition of cultivating the three fundamental energies.

**Documented modern synergies**: Ashwagandha + Rhodiola for anxiety + cognitive fatigue at once. Reishi + Cordyceps for immune and energetic support. Shatavari + red Maca for the feminine in perimenopause.

**To avoid**: Rhodiola late in the day. Cordyceps + caffeine can be too stimulating. All the adaptogens at once in very high dose — the systemic architecture asks for patience, not saturation.

Nuggets and legends — adaptogenic sparks

The word 'adaptogen' turns 79 in 2026. Coined in 1947 by Nikolai Lazarev, pharmacologist at the Leningrad Military Academy, in the context of Soviet research on the performance of soldiers and pilots. From that time on, Russian pharmacopoeia methodically studied Eleutherococcus senticosus, Rhodiola rosea, Schisandra chinensis, Aralia mandshurica. A library of more than 1,000 Soviet studies on adaptogens exists — little of it translated into English.

The concept of *rasayana* in Ayurveda predates the concept of the adaptogen by nearly 3,000 years. The Charaka Samhita (~1000 BCE) devotes a whole chapter (Chikitsa Sthana, ch. 1) to the rasayana — the plants of longevity and regeneration. The grammar is different — not 'raise resistance to stress' but 'restore the vital essence (rasa)' — but the intuition is identical.

Wild Cordyceps sinensis is one of the most expensive materia medica in the world — up to 100,000 USD per kilogram in the markets of Lhasa. Its annual harvest (May–June) employs hundreds of thousands of Tibetan nomads at 4,500m altitude, and accounts for 40% of the GDP of certain Tibetan prefectures (Winkler, 2008, Asian Medicine).

Schisandra is one of the very few plants in the world that holds all five flavours of traditional Chinese medicine (sweet, sour, bitter, salty, pungent). In TCM thought this property makes it a 'complete' plant that balances the five organs (heart, liver, spleen, lung, kidney) at once. No other plant has this profile.

Maca was the subject of an international patent battle between 2001 and 2003, when an American company (Pure World) filed patents on compounds extracted from Maca. The Andean communities, backed by the Peruvian government, contested those patents as biopiracy. The patent was partly annulled in 2003 — one of the rare cases of an ethnobotanical victory against industrial appropriation.

Wild Reishi is extremely rare — fewer than 1 in 10,000 dead tree stumps bear it. This is why, in ancient China, Reishi was reserved for the emperor and for wandering Taoists — said to be able to find it by a 'gift of the spirits'. Modern cultivation on wood substrate (since the 1970s) has democratised access, without abolishing the respect owed to the plant.

The Charaka Samhita prescribes Ashwagandha not in uniform daily doses but in *Kalpa* — a protocol of 30 to 90 days during which the patient lives in a controlled environment (natural light, simple food, morning meditation). It is this context that makes the course, not the plant alone. Modern Western pharmacology, which isolates the molecule from its context, loses this dimension.
