How the plant of the gods invites us to redefine human optimisation
True optimisation begins not with control, but with connection.
In a world that measures, tracks and optimises every data point of our biology, the heart often gets left behind. The modern biohacker might measure their glucose curve or track their REM sleep, but rarely do they ask: how open is my heart today?
At Herbal Cacao, we believe the next step in human potential is not about becoming faster or sharper, but about becoming more attuned to our bodies, our emotions and the living Earth that sustains us. And few plants embody this more fully than ceremonial cacao, the ancient heart medicine of the Maya traditions. When we bring her into our daily ritual, we are not just hacking our biology. We are bringing it into harmony with spirit.
My name is Sharon Fernie and I am the founder of Herbal Cacao, where we share high-quality ceremonial cacao blends with herbs, spices and mushrooms. I have a deep passion for holistic wellness and ancient traditions, and through Herbal Cacao our mission is to support our community on their journey of self-discovery and spiritual growth, while spreading awareness of the profound benefits of ceremonial cacao and other medicinal herbs, adaptogens and mushrooms. Read more about my story.
Here in the Herbal Cacao Journal, I explore the fascinating world of active medicinal compounds, rituals, ancient healing practices and modern wellness, often woven together with experiences from my own life. So whether you are experienced or just beginning your holistic journey, this is your invitation to deepen your understanding of sacred plants and their profound effect on body, mind and spirit.
What is heart-centred biohacking?
Traditional biohacking often focuses on performance, optimising the body as if it were a machine. Heart-centred biohacking shifts the paradigm: it sees the body as a living ecosystem, a vessel for consciousness, creativity and compassion.
It invites us to explore optimisation through presence rather than pressure. It honours emotional intelligence as much as mental clarity. It is a practice of aligning heart, mind and nervous system, so that energy can flow, intuition can deepen and resilience can become our natural state. Instead of only asking how well we function, it asks:
- How aligned is my energy with my purpose?
- How calm and steady does my heart feel?
- How connected do I feel to life itself?
When we bring ceremonial cacao into this landscape, we weave the scientific together with the sacred, caring not only for how we function, but for how we feel.
Cacao as nature's original biohack
Long before nootropics and smart supplements, cacao was honoured as a plant of great power, a messenger between people and the divine. In Mesoamerican traditions, cacao was shared at the most important moments of life and seen as a drink that opens the heart. Today, science is starting to look at what is actually inside her.
Theobromine, the heart-warming compound
Cacao's main natural stimulant is theobromine. A 20 g cup of pure cacao contains around 260 mg of theobromine and only around 16 mg of caffeine. Theobromine is a much milder stimulant than caffeine and works more slowly, which is why many people describe the energy of cacao as calm, warm and steady rather than sharp.
Flavanols and blood flow
Cacao is naturally rich in flavanols. According to the European Food Safety Authority, cocoa flavanols help maintain the elasticity of blood vessels, which contributes to normal blood flow. This effect is obtained with a daily intake of 200 mg of cocoa flavanols.
The bliss molecule
Researchers have found small amounts of anandamide, often called the bliss molecule, and related compounds in cacao. How much these contribute to the way cacao makes us feel is still being studied, but it is a beautiful link with the traditional view of cacao as a joyful, heart-opening plant.
Minerals for body and mind
Cacao is a natural source of magnesium and iron. Magnesium contributes to the normal functioning of the nervous system, to normal psychological function and to the reduction of tiredness and fatigue.
In other words, cacao invites us to care for our biology through the pathway of pleasure, ritual and heart connection.
From data to devotion: heart coherence
Heart coherence is a term from researchers such as the HeartMath Institute. It describes a smooth, steady and harmonious heart rhythm pattern, often reached through slow breathing and positive emotions like gratitude and love. Their research links coherence with feeling calmer, more focused and more emotionally balanced. Read more in heart coherence, ceremonial cacao and the Earth.
Cacao is not a shortcut to coherence, and there are no studies on cacao and heart coherence yet. But a cacao ritual naturally brings together the things that support it: slowing down, breathing deeply, placing your attention on your heart and feeling gratitude. As warmth spreads through your chest and you sip slowly, your body has a chance to remember safety.
When the heart becomes coherent, the whole body listens.
Ritual as the ultimate nervous system technology
While modern biohacking relies on gadgets, ancestral wisdom uses ritual. When you create a daily cacao ritual, you are inviting your body into peace rather than performance. Try this:
- Set your intention. What part of yourself do you want to open or strengthen today?
- Prepare your cacao mindfully. Warm 20 g of ceremonial cacao slowly with water or plant milk. Let each movement be a meditation.
- Breathe. Hold your cup, place your attention on your heart and take 5 slow breaths.
- Sip slowly. Feel the warmth spreading through your chest.
- Listen inward. Let insights arise from the stillness.
- Move or write. Dance, journal or meditate, and let your body express what your heart wants to say.
20 g is a lovely daily cup. For a deeper meditation you can use 20 to 30 g, and for a ceremony 30 to 50 g, never more than 50 g. Find the full guide in how to use ceremonial cacao.
The Herbal Cacao biohacker's toolkit

Each cup becomes a ritual that cares not only for your metrics, but for your mood, your creativity and your connection with yourself.
Beyond the self: conscious biohacking for the planet
Heart-centred biohacking reaches beyond the individual. When we choose ethically sourced ceremonial cacao, we support regenerative agroforestry and the farming communities who grow her, such as the cooperatives of FEDECOVERA in Alta Verapaz, Guatemala, who grow cacao with care for both people and planet. 2% of every Herbal Cacao sale goes back to the cacao communities through our reciprocity programme.
In this way, our personal growth feeds collective care. Every sip becomes a small revolution, a reminder that true optimisation is interconnection.
The future of biohacking is heart-led
As we move toward a new way of looking at wellbeing, cacao reminds us that evolution without empathy is incomplete. Heart-centred biohacking is not about control, but about communion. It invites us to blend science with ceremony, data with devotion and performance with presence.
Each morning cup becomes an act of remembering that the greatest upgrade available to us is love itself.
A ritual invitation
Tomorrow morning, before you open your laptop or check your metrics, prepare your cacao. Close your eyes. Feel your heartbeat. Whisper:
I open to the wisdom of my heart. May my energy serve love today.
Then sip, slowly and mindfully. You have just brought your humanity back into the centre of your day.

Frequently asked questions
What is heart-centred biohacking?
It is an approach to wellbeing that values emotional balance, intuition and a calm nervous system as much as performance. Instead of only tracking data, it uses presence, breath and ritual to reconnect with the heart.
Does ceremonial cacao contain caffeine?
Only a little. A 20 g cup contains around 16 mg of caffeine, compared to around 260 mg of theobromine, a milder and slower stimulant. That is why the energy of cacao often feels calm and steady.
How much ceremonial cacao should I use for a daily ritual?
20 g is a lovely daily cup. For meditation you can use 20 to 30 g, and for a ceremony 30 to 50 g, never more than 50 g.
Can cacao bring me into heart coherence?
Cacao alone does not create heart coherence, and it has not been studied for this. But a cacao ritual with slow breathing, attention on your heart and feelings of gratitude brings together the practices that are known to support it.
