So grateful for the Quick delivery and the dream beans are so beautiful! Also big warm thank you hug for the gifted lotus, will def try it during meditation!!! I did some tea on the calea and oh my was it bitter. Took a spoon full of honey after the tea, brushed my teeth and off to bed. Listened to a friends meditation music and dozed off to sleep. Can't recall or remember right now what I dreamt off but I remember laughing and hearing myself laughing even do I slept. Overall a beautiful experience, woke up feeling joyful and open hearted. Will drink it again. I use to lucid dream alot many years ago so looking forward to it again. The beans...not sure if I will eat them or keep as talismans. Thank you for this good medicine! 🙏🏼🌿😊❤️

We answer.
What is Calea zacatechichi?
Calea zacatechichi (today Calea ternifolia) is a small Asteraceae with yellow flowers, native to the mountains of Mexico, that the Chontal of Oaxaca name thle-pela-kano — 'herb of the gods'. She is a plant of the dream, an oneirogen — drunk as an infusion in the evening not for what she would do in the day, but to make sleep more porous and the dream more present on waking.
What are the effects of Calea zacatechichi?
In the Chontal tradition and the ethnobotanical literature, Calea is described as an oneirogen — a plant that touches the quality of the dream more than the state of waking. Schultes, Hofmann and Rätsch speak of a subtle psychoactive effect, described as 'dreamlike'. No hallucinogenic constituent has been isolated from her, and her effects are described, never promised. She is not a medicine.
How do I prepare Calea zacatechichi as an infusion?
Count about a teaspoon of whole dried leaves per cup, infused 5 to 10 minutes in simmering water (~80 °C), in the evening before sleep. Prepare yourself for the bitterness — she is the plant's signature. Some sweeten her lightly with honey, lemon or mint; others drink her as she is, as a discipline of the crossing.
Why is Calea zacatechichi so bitter?
The bitterness is her signature. The Spanish baptised her yerba amarga, 'the bitter herb', and the Nahuatl name zacatechichi already says the bitter. Dale Pendell notes that this bitterness is so striking it can eclipse the finer nuances of the experience. In the INFUSE reading, she is her first word — the commitment she asks before she gives anything.
Does Calea zacatechichi cause lucid dreams?
Tradition and research describe her mainly as a plant that makes dreams sharper and better memorised, not as a guarantee of lucid dreaming. Many dream practitioners associate her with a dream notebook and an intention set down before sleep. Effects vary from one person to another, and nothing is promised.
Is Calea zacatechichi legal in my country?
Calea is reportedly legal in most countries, and reported illegal in Poland (since 2009) and in Louisiana, in the United States (since 2005). The status may vary by jurisdiction — verify the regulation of your country before any purchase or travel.
How much Calea zacatechichi should I use?
INFUSE suggests starting soberly, with a teaspoon of dried leaves in an infusion in the evening, then adjusting according to one's own sensitivity. The tradition reported by Pendell uses a stronger infusion, a good full handful of leaves per cup. These are traditional markers, not a posology; start low to observe how your body responds.
What precautions with Calea zacatechichi?
To be reserved for bedtime — do not drive or operate machinery after drinking her. Avoid during pregnancy and breastfeeding (insufficient data) and in children. Her bitterness can cause mild nausea at high concentration, so start gently. With a sedative or psychotropic treatment, ask for medical advice. Asteraceae allergy — caution.

For those who want to descend below the page — botany, chemistry, the long history, and what the studies say. Descriptive register: we name, we situate, we promise nothing.
### Botany and identification
Calea ternifolia (long written Calea zacatechichi, a name still widely used in trade) is an Asteraceae — the great family of composites, the one of chamomile, echinacea and the daisy. She is a branched shrub reaching about 1.5 m (rarely up to 3 m), with small oval leaves crisped at the edges and small yellow flowers, sometimes whitish. The underside of the young leaves turns violet, and the foliage is of intense green (Rätsch).
Her determination is notoriously delicate: Calea is easily confused with other close species of the same genus, and several "Calea" in trade are not always the right plant. This is one of the reasons why a traceable supply chain counts as much here as for any dream plant. In Mexico, locals also use the leaves as an insecticide (Pendell) — a profane use that reminds us that before being the dream herb, Calea is first an everyday plant in her region of origin.
### Phytochemistry — a plant that keeps her secret
The most remarkable fact about Calea is what one has not found: no constituent with hallucinogenic properties has been isolated from the plant. This is the central observation of Plants of the Gods (Schultes, Hofmann & Rätsch, p. 38) — the plant contains germacranolides, sesquiterpene lactones, and her subtle psychoactive effect is described there as "dreamlike".
More recent analyses name several compounds: germacranolide sesquiterpenes (the caleicines and caleochromenes, signatures of the Asteraceae family), abundant chlorogenic acid (a common antioxidant in the plant kingdom), and acacetin, a flavone. No major alkaloid. Germacranolides also have chemotaxonomic value within the Calea genus — they help classify species (Ferreira et al. 1980, cited by Rätsch). But the precise source of the activity remains unknown: it seems distributed across several compounds in synergy rather than carried by a single molecule. Calea is, in this sense, a plant that resists isolation — she does what she does without anyone yet knowing quite how.
### Lineage and long history — from the Chontal to Harvard
Among the Chontal of Oaxaca — descendants of the Olmec, the oldest Mesoamerican civilisation —, in the southern Mexican sierra, the plant carries the name thle-pela-kano, "herb of the gods" or "leaf that clarifies the senses". The Maya know her under other names, including xikin, "plant of the dove". In Nahuatl, one speaks of tepetlachichixihuitl, "the bitter plant of the mountains"; popular Mexican names keep the trace of the everyday, such as zacate de perro, "dog herb", or Bejuco chismuyo, Hoja Madre, Prodigiosa (Rätsch). The divinatory use is documented in ethnographic accounts since at least the 19th century, and is likely much older: an infusion of dried leaves is prepared, drunk in the evening, one lies down in a dark place, and one seeks in the dream an answer — diagnosis of a trouble, search for an object or a person, guidance.
It was the American ethnobotanist Thomas MacDougall who, in the 1960s, brought this Chontal use to the attention of research, and transmitted samples to Richard Evans Schultes, at Harvard — the thread that would lead to the inscription of Calea in Plants of the Gods and to her global visibility. Rätsch finally reports a curiosity of reputation: the Melanesian "dream fish" (Kyphosus fuscus) is said to produce dream effects comparable to those of Calea — a kinship of reputation across the oceans.
### What the studies report
In 1986, a study examined by EEG subjects who had ingested Calea, in the context of research on her dream effects (Mayagoitia, Díaz & Contreras, cited by Rätsch). The reports of this literature describe, at a moderate dose, an increase in light sleep stages and in the number of spontaneous awakenings — which, mechanically, favours dream recall, since awakenings on exit from paradoxical sleep allow one to grasp the content. Studies also report a modified perception of time elapsed and a slight slowing of reaction time; a mild antinociceptive effect has been observed in animal models. These observations are descriptive: they describe what researchers have measured, not a promised benefit.
Dale Pendell, in Pharmako/Poeia, ranks Calea among the somnifera, the plants that transform sleep, and describes her effect as oneirogen. He also transmits an inner marker of tradition: the signal that the plant takes effect arises when one perceives one's own pulse, the beats of one's heart. It is the 1986 study, more than any other, that brought the very word oneirogen into the vocabulary — a plant, in a way, forced research to name a category that did not exist.
### Safety and frame of use
Calea is an evening plant, to be reserved for bedtime: one does not drive and does not operate machinery after drinking her. Tradition and contemporary literature describe her as a plant of cycle rather than of continuous daily use — a few spaced nights, with pauses. Her extreme bitterness can cause mild nausea at high concentration, which invites starting low. At very high doses, rare, reports mention salivation, nausea and digestive discomfort; an in vitro study has raised possible nephrotoxicity at high prolonged doses — one more reason to respect the spaced rhythm of tradition.
Like all Asteraceae, Calea can concern people allergic to this family (chamomile, echinacea, ragweed). Pregnancy, breastfeeding and children: to be avoided, insufficient data. With a sedative or psychotropic treatment, medical advice is necessary before any use. Concerning legality, Calea is reportedly illegal in Poland (since 2009) and in Louisiana, in the United States (since 2005), and legal in most other countries — a status to verify according to one's jurisdiction. This page documents a traditional dream use; she carries no health promise and Calea is not intended to diagnose, treat or prevent any illness.
