Postpartum, menstrual cycles, menopause, fatigue, imbalances: FeminAlchimy supports you through traditional Mexican care, biomagnetism, and herbal medicine to rediscover a deep balance between body, soul, and mind.

My mission

My conviction is that every woman has within her the resources to regain her balance.

My role is to be that catalyst, that interpreter who helps you reconnect with your potential whatever your age or the moment of your life.

Combining the precision of functional health with the wisdom of Mexico's holistic traditions, I offer you tailored, in-home guidance to deeply transform your vitality.

FeminAlchimy Care

Biomagnetism

Listen to your body's messages differently

At the core of biomagnetism lies a fundamental principle: the symptom is not the disease, but a signal. This gentle, non-invasive, and holistic approach allows for the evaluation of your energetic balance and provides a comprehensive assessment of your vitality.

The objective? To restore the overall harmonization of your being on the physical, energetic, and emotional levels. A practice that is fully part of an integrative health approach, complementing conventional medicine.

Rebozo care

An enveloping, sacred, and deeply feminine ritual

The Rebozo care is a ritual of grounding and celebration, ideal for accompanying all major transition stages: motherhood (postpartum), grief, separation, career change, or simply the need to close a cycle and turn a new page.

Regeneration & Vitality

Custom protocols to cleanse and revitalize your energy

Personalized guidance focused on natural health to deeply detoxify the body: herbal intestinal hygiene cleanses, liver function support, heavy metal elimination, and the revitalization of vital energy. Protocol followed remotely, individually or in a group.

Transformation Pathway

Comprehensive support to reveal your inner balance

Inspired by traditional Mexican medicine and integrative health, this exceptional journey offers comprehensive, personalized support. It is particularly recommended for navigating pre-menopause, menopause, a period of convalescence, exhaustion, or a demanding life transition.

Your journey in 3 steps:
1 – Understand: In-depth interview, vitality assessment, and biomagnetism session.
2 – Rebalance: Customized body care tailored to your current needs.
3 – Integrate: Rebozo Care & global guidance assessment.

Hello, I am Amandine Sellier!

Certified practitioner in Traditional Mexican Medicine (training recognized by the Mexican Ministry of Health) and passionate about herbalism.

Driven by the rhythm of women's cycles, the wisdom of ancestral traditions, and holistic approaches to well-being, I created FeminAlchimy to offer women a sanctuary of peace:
a space to slow down, listen to their bodies and reconnect with their essence.

For 10 years, in the heart of the Riviera Maya near Tulum, I trained with local traditions and founded the Mamà Hierbas project, dedicated to traditional herbalism and ancestral holistic practices.

Rich with this journey and this global vision of women, I am happy to return to my native land, in the heart of the Opal Coast, to support the women of the region through their major life stages and their transformation processes, whether physical, emotional, or energetic.

A synergy of practices
ancestral and intuitive

My coaching is centered around the encounter between different wellness traditions:

Eager to honor and perpetuate this precious knowledge, I am committed to passing it on.

I also offer training courses, both in-person and online, for those who wish to learn about the use of medicinal plants, the art of Rebozo care, or natural women's health coaching.

Every woman is unique.

I welcome you to the Opal Coast and online for individual care or transmission sessions to gently guide you toward your overall balance.

Ready to reharmonize your health, wherever you are?

Vitality assessment, women's functional health, and tailored remote protocols (consultations in French, English, and Spanish).

"I have been working with Mama Hierbas for a year and it is an extraordinary experience. She is so intuitive, authentic, and incredibly knowledgeable in her many fields. The work we have done together has brought magnificent changes to my health (physical, feminine, mental, emotional, and spiritual). Wonderful feminine wellness rituals. Biomagnetic purification sessions. Excellent detox products. During my first biomagnetic session, I felt such an intense energetic purification that it was simply magical. Her feminine wellness rituals have been a great emotional comfort and have significantly improved my menstrual cycle. I am so happy to have met her! A wonderful healer – we love you!"

«Before consulting Amandine, I was completely lost dealing with recurring digestive issues. I was truly caught in a cycle of medical wandering until a friend, who had completed her parasite cleanse, recommended her guidance. Right from the start, I benefited from daily support and a tailor-made, exceptionally attentive approach. Amandine is always there, incredibly attentive, and truly understanding. Thanks to her, I was able to realize the limits of traditional medicine and finally put words to what no one had identified before. Today, I have recovered incredible energy and much better digestion. It is a process that requires consistency, but the benefits are definitely there. Everyone should consult Amandine: she is a lovely practitioner, extremely caring, and endowed with precious knowledge.»

«Initially, I was quite skeptical: I am a very logical person and I need to feel things concretely to believe in them. Yet, from the very first biomagnetism session with Amandine, all my doubts vanished. The next morning, it was as if my entire body had been hit with a "reset" button: I woke up pain-free, with real energy and a sense of calm and inner peace. Beyond the in-person sessions, I continued with remote follow-up. It is a deep, foundational process, both physical and emotional, that has literally changed my life. Today, Amandine has become an essential reference for my health: her knowledge of natural and holistic medicine is of a rare richness. I recommend her blindly!»

«Thanks to Amandine's coaching in biohacking and lifestyle habits, I relearned how to discipline my eating habits while still enjoying myself. This process was a true purification on every level—physical, mental, emotional, and energetic. I felt guided and listened to. This journey allowed me to validate the rhythms my body was naturally asking for (such as intermittent fasting), soothe my relationship with food, and rediscover a true sense of inner security. It is an approach rooted in self-love and sovereignty over one's own body. Thank you, Amandine, for your invaluable support, imbued with kindness, determination, and enthusiasm. I felt deeply supported and secure.»
