Botanical Biohacking

In this episode, you'll learn:

- Why the eyes can offer clues about nervous-system arousal - How the pupils, noradrenaline, and alertness are linked - Why narrow, screen-focused attention can keep the mind activated - How widening your visual field may help signal safety and relaxation - What lateral eye movement has in common with walking and other calming practices - A simple eye exercise Dr. Miles suggests for settling back to sleep

Dr. Miles also unpacks a line from the "Yin Fu Jing: "The heart is born from things and dies from things." He considers what it means to guide your attention outward—or zoom out—when you feel caught in a cycle of stress, overwork, or restless nights.

Listen for a fresh perspective on sleep and a simple practice to try when you wake in the middle of the night.

What if the things holding you back aren't obvious and aren't fate? In this episode of the Botanical Biohacking Podcast, Dr. Andrew Miles explores how subconscious barriers can shape our health, habits, and sense of what's possible.

Andrew shares a simple practice that prompted unexpected changes: asking, "Where are the hidden borders of your life?"without trying to force an immediate answer. He reflects on how insights can emerge through dreams, symbols, and moments between sleep and wakefulness, and how seeing your life from a third-person perspective can reveal patterns you've taken for granted.

Drawing on Taoist teachings and Celtic stories, including Finn McCool's search for the salmon of wisdom, Andrew considers why old conditioning can feel like an unchangeable destiny, even when it no longer applies. He also discusses his work in Chinese medicine, Chorus for Life, and the tension between promoting health work and avoiding the exaggerated claims he sees in parts of the biohacking world.

This episode is for anyone curious about self-inquiry, Chinese medicine, Taoist wisdom, and the hidden patterns that may be shaping their lives.

Grief does not just live in your mind. It can affect your gut, your heart, and even your immune system. This episode explores how ancient Chinese medicine and modern neuroscience both point to a striking truth: loss can become physical, even when the suffering is not visible.

Andrew begins with a sixth-century story of a young woman whose grief becomes overwhelming after she sees a cherished object that belonged to her mother. He then turns to the scholar Yan Zhitui, who recorded cases of "broken intestines" and described how grief can affect people in very different ways.

You'll discover: - How grief can affect appetite, digestion, gut sensitivity, and the heart - How the gut communicates with the brain through the vagus nerve, hormones, and immune signaling - What stress responses involving CRH and mast cells can mean for the digestive system - Why intense emotional shock can have serious effects on the heart - How three classical Chinese formulas, Chaihu Shugan San, Tong Xie Yao Fang, and Zuo Jin Wan, have been studied in connection with digestive conditions

Blending historical accounts, modern research, and traditional Chinese medicine, Andrew explores why grief is not always easy to see from the outside. Some people express their sorrow through tears, while others may carry it quietly in the body.

For anyone who has experienced loss or wants to better support someone who is grieving, this episode offers a compassionate perspective on the connection between emotion and physical well-being.

A fortune teller says your future is fixed, and for most people, that can become a life sentence. This episode explores how one man challenged that prediction, changed his trajectory, and discovered that what looks like destiny may be a pattern that can be changed.

Dr. Andrew Miles tells the story of Liao Fan and the monk Yun Gu meets Liao Fan sitting in stillness, he sees not enlightenment but resignation, then offers him a practical path toward change.

You'll discover: - How wandering thoughts and fixed expectations can keep people stuck - What "Destiny is made by me" means for fate, effort, and personal growth - The six habits Liao Fan recognized as standing in his way - How a daily merit-and-fault ledger became a tool for tracking change - Why self-monitoring, self-efficacy, and small experiences of progress matter

Andrew connects this centuries-old story with modern neuroscience and behavioral science, including the default mode network, nocebo effects, and the power of recording your own behavior. He also explores why a prophecy can shape expectations, why stillness alone isn't the same as transformation, and how a daily record can make progress visible over time.

If you've felt limited by habit, fear, or someone else's prediction about your future, this episode offers a grounded way to reconsider what may be possible and what you can begin changing.

Seeing lights while meditating can be alarming or lead people to fantastical conclusions. Here Danel Zhang, an inheritor of the Wu Liu pai school fo Taoist yogic Alchemy describes what is really happening and I add some musings based on current neuroscience.

Neither believe nor disbelieve what you see, neither advance nor retreat from it. Allow any sensations to find their bay back into the smooth functioning of the body and spirit.

What happens when a fortune teller can name your exam results, your promotions, and even the exact hour of your death? One Chinese scholar's life is shaped by a prophecy so precise it seems impossible to escape. Until the real question becomes whether fate is fixed, or whether the brain learns helplessness when it stops seeing a way out.

Dr. Andrew Miles turns a centuries-old Ming dynasty story into a striking exploration of destiny, psychology, and Chinese medicine. A boy once destined for the imperial exams is redirected into studying herbs and pulses by his mother. Then he meets Kong from Yunnan, a mysterious figure who claims to hold the true transmission of Master Shao's Huangji numerology. What follows is a life mapped in exact ranks, dates, and outcomes. A growing sense that the future has already been written.

In this episode, you'll discover why Liaofan's story resembles a real-life experiment in learned helplessness, how Kong's predictions about exam ranks, rice stipends, promotions, and death unfold with unnerving accuracy, why the story changes when one prediction appears to be wrong, how Dr. Andrew Miles connects this ancient account to modern research on stress and the brain, and why Chinese medicine's concept of qi stagnation parallels the brain's response to uncontrollable stress.

Andrew also discusses the traditional formulas Yueju Wan and Kai Xin San, used for stagnation and low spirits, and connects them to animal studies exploring stress, passivity, and resilience.

For anyone who has ever felt stuck, resigned, or quietly stopped trying in one area of life, this episode offers a new way to consider whether you're facing a true limit or a boundary your brain learned to expect. It's a thoughtful conversation about control, healing, and the possibility of change.

Perfect for listeners interested in Chinese medicine, neuroscience, psychology, and the question of whether we're shaped by fate or by what we learn to believe is possible.

What if the way people respond to you is being shaped before you say a word? In this episode, Dr. Andrew Miles explores how heart rate variability (HRV), nervous system regulation, and emotional synchrony may influence trust, conflict, and connection.

From couples caught in escalating arguments to people who naturally draw a group's attention, Andrew looks at how our bodies can affect the rhythm of an interaction. He discusses how stress and low HRV may shape the way we read facial expressions and tone, and how calm, breathing, and regulation can help people feel safer and more connected.

In this episode, you'll hear about:

- How heart rate synchrony can begin before a conversation - The role of emotional contagion in both conflict and connection - How HRV relates to social stress, loneliness, and nervous system regulation - Why some people seem to set the rhythm of a group - The connections Andrew draws between breath, posture, the vagus nerve, and HRV - His use of HRV sensors and EEG headsets in his Chinese medicine practice in Chengdu

Andrew also shares traditional Chinese medicine and Taoist perspectives on resonance and the heart's capacity to rest. He closes with ways to observe HRV over time and discusses the customized support offered through his practice.

The episode delves into the philosophy of herbal use, emphasizing that more isn't always better. It introduces three main approaches to health, highlighting the importance of creating space for healing. Modern health challenges, particularly the 'heart coldness' prevalent in today's society, affect relationships. A significant insight is the connection between the heart and spleen, stressing that true healing comes from embracing emptiness rather than avoiding it. The conversation flows from practical herbal philosophy to deeper emotional and spiritual healing.

I paid enough to buy a car for billionaire brain training. Was it worth it?

A scholar meets a rabbit fairy?? to discover how his headaches are caused by an imbalance in his gut brain axis? Yep, apparently Song dyansty college students were doing shrooms.
