Cebil (Anadenanthera Colubrina)

Anadenanthera Colubrina, more commonly known as Cebil is a South American tree with mimosa-like leaves and a very thorny trunk. Several parts of the tree including bark, fruits, and seeds contain powerful psychoactive substances including bufotenine, 5-MeO-DMT, and DMT. Cebil is one of the oldest psychoactive substances and has been given a high priority conservation status in Brazil.

Some of the other names for Anadenanthera Colubrina are Willka, Wilca, Vilca, Huilca, Huilco, Wilco, Willka, Curupay, Curupau, Angico, and Cebil.

History of Cebil

Anadenanthera Colubrina or Cebil is a South American tree closely related to Yopo (Anadenanthera Peregrina). It is found in various parts of the continent including Argentina, Bolivia, Peru, Brazil, Ecuador, and Paraguay. The Cebil tree can be described as a fast-growing plant and can grow from anywhere in between 5m to 20m high.

Anadenanthera Colubrina is known by many names throughout South America including Willka (also spelled Wilca, Vilca, Huilca), which in the Quechua languages means sacred. The indigenous people of South America have been using Cebil (just like Yopo and the drink Ayahuasca) in shamanistic rituals for hundreds of years and consider it to have magical properties.

The effects of Cebil seeds are similar to that of Yopo or LSD only less intense and for a shorter duration.

Archeological evidence found all over Argentina, Peru, Bolivia, Chile suggest that Cebil has been used as a hallucinogen for over 4000 years.

Effects of Cebil

Cebil seeds when administered properly have a psychedelic effect and can help:

  • Induce visions
  • Relax
  • Bring powerful dreams

Cebil Uses and Dosage

Anadenanthera Colubrina or Cebil seeds once toasted and dried can either be chewed or insufflated. Unlike many other herbs, brewing Cebil seeds into a tea is not a suitable way of consuming it.

To toast Cebil seeds, heat a frying pan on medium heat and slowly roast the seeds until you hear them pop. Make sure to not overheat or burn the seeds as that will make them lose their potency. As soon as you hear the Cebil seeds burst open, take them of fire and remove the husk (outer brown shell). Reheat the inner white pit on low heat until it becomes hard and grainy. Grind the hardened, roasted inner part of the seed with a coffee grinder or mortar into a fine powder.

Mix 2 parts Cebil seed powder, 1 part calcium hydroxide, and 1 part baking powder. Add a few drops of water so it becomes a dough-like substance. Heat the mixture gently until it's dry. Grind into a fine powder. Your Cebil seeds are now ready to be used as snuff. If the seeds haven’t dried properly, grinding them will turn them into a sticky paste that is unfit for consumption.

  • Insufflation – Using Cebil seeds as snuff is supposed to have a fast onset. It is a great way for those with prior experience with shamanistic psychoactive substances or someone looking for immediate effect.

    Recommended Dosage - To achieve intense hallucinations, a dose of 1g is recommended. However, if you are using Cebil for the first time, it is best to start with a milder dose of 200 – 500mg. One can even try with even smaller doses to see the effects and then increase the dosage with time.

    Another way of dosing Cebil is by the number of seeds. A dose of 1 to a maximum of 4 seeds is recommended for insufflation.

  • Chewing – Though not a popular or suggested method, some people prefer to chew Cebil seeds. The dried toasted seeds are consumed with beer or any other drink by more seasoned users of psychedelic substances.

    Recommended Dosage – For first-time users, it is best to try Cebil seeds in snuff form, starting with small quantities. However, if you are intent on taking the seeds orally, start with 1 seed and then gradually go up to 2 seeds. It is not recommended to take more than 3 seeds orally.

How to grow Cebil plant

It is relatively easy to grow a Cebil plant from seeds. Cebil seeds should be pre-soaked in sterile water for 24 hours. Boil the water and let it cool down before soaking the seeds. Cebil seeds and seedlings are prone to rot. It is best to germinate them in sharp horticulture sand; both perlite and vermiculite are suitable. Ideally, the sand should also be sterilized.

Cebil seeds require a minimum 22 °C temperature, a constant source of heat is essential for germination. If choosing to use perlite or vermiculite sand, plant the seeds pots or seed trays about 1cm below the surface, and water lightly using a spray bottle. Make sure the growing medium is moist but not wet. Let the pots/trays stand for a while for the excess water to drain and then place them in a bright area away from direct sunlight. It is important to ventilate the pots or trays every day to prevent mold.

Under favorable conditions, Cebil seeds should germinate within a week. Once the seedlings start showing from the soil, start acclimatizing them for drier conditions, by providing progressively more ventilation, and watering sparingly but regularly. Allow the growing medium to become almost dry between watering. Watch for any signs of mold and make sure the conditions are not too hot, either of the two will quickly kill the seedlings.

Start introducing fertilizer by occasionally adding it to the water, beginning with ¼ of the recommended strength, upping the dose gradually.

Potting and Re-potting

For the first year, Cebil plant grows slowly and still requires free draining soil such as 50% cactus compost and 50% perlite.

In the second year, re-pot the Cebil plant in a medium that while can be rich in organics, is still fairly free draining. 50% peat s0075bstitute, 25% coconut coir, and 25% perlite can be a good medium composition.

A 2cm layer of gravel or broken crocks at the base of the pot will provide the required extra drainage. A 1cm layer of fish tank gravel or cactus top dressing on the surface will prevent the perlite from floating to the surface and prevent excessive evaporation. Once established, the Cebil plant can benefit from regular fertilizer feeds during the summer months. It should soon start growing vigorously.

Caring for Cebil Tree

The Cebil tree enjoys warm sun and free-draining soil. They cannot tolerate being waterlogged and can only withstand light frost. It's best to bring the plant indoors during the winter months.
