How It Works, Your Journey to Vitality Simplified

1. Book Your Consultation: Email me to schedule your initial deep-dive session and get started on your intake.


2. Dive Deep Together: In our call, we'll explore your intake information, health history, goals and the deeper patterns at play.


3. Receive Your Custom Plan: Within one week, you'll receive your personalized protocol and implementation guide.


4. Approve & Relax: You review and approve your personalized herbal recommendations, then I handle everything else. Here's what sets us apart: because herbalism is a form of traditional medicine, many of your herbs can be custom-formulated specifically for your unique protocol—simplifying your routine and making it easier to stay consistent. If you had to develop relationships with formulators, compounders and quality suppliers on your own, it could take months or even years to establish the level of product care and quality I provide. I've already done that work for you.


5. Your Herbs Arrive: A curated package arrives at your door, with everything labeled and ready to use.


6. Begin Your Transformation: You start your journey with my full support, following a clear and simple plan.


7. Optimize & Thrive: We connect on follow-up calls to celebrate your progress, refine your protocol, and ensure you feel vibrant and alive.

About Soul Herbalism

The Art and Science of Soul Herbalism

At Know Thy Medicine, we practice Soul Herbalism—a profound approach that blends modern nutritional science with the ancient wisdom of plant intelligence. It recognizes that true, lasting wellness emerges when we nourish our whole being.

This work is grounded in a simple, powerful framework: that a healthy human soul has three core faculties that plants can help us awaken and balance. This is the depth of approach that makes my work so transformative. I'm not just addressing symptoms, I'm partnering with you and the intelligence of nature to support your entire being.

The Thinking Faculty

We use specific herbs to cultivate clarity, quiet mental chatter and enhance focus, moving you from overwhelm to peaceful discernment.

About Sandi Nizzoli

Your partner in wellness and healing

I'm Sandi Nizzoli, a Nutritional Therapy Practitioner (NTP) and Clinical Herbalist. My work is born from a deep belief that the body has an innate capacity to work out of its vital force and that nature provides the most powerful tools to support that journey.


My approach is both clinical and spiritual. I am trained to understand the intricate biochemistry of the body, but I also honor the soul's journey and the profound relationship we can have with the plant world. I serve as a guide and a bridge, helping you understand the language of your body and connect with the healing intelligence of herbs.


I founded Know Thy Medicine to offer a level of care I saw was missing: a service that is deeply personalized, scientifically grounded and completely supportive, removing the overwhelm so you can focus on what truly matters, your wellness.

Common Questions

Please reach us at Sandra@knowthymedicine.com if you cannot find an answer to your question.

A: Not at all! I work with clients virtually across the country. Consultations are held via Zoom and all products are shipped directly to your home.


A: This is a critical part of our initial consultation. I am trained in herb-drug interactions and will create a protocol that is safe and complementary to your current healthcare plan, always working with the utmost care and respect for your medical needs.  In addition it is important to note that NTP’s and Herbalists are part of your overall healthcare team, not a replacement for PCP, rather, complimentary to.


A: Because each body responds differently, changes can emerge in different ways and at different paces. Some people notice early shifts in energy, digestion, sleep or mood, while for others the changes are quieter and build over time. Sustainable, meaningful change is typically the result of steady, longer-term support rather than quick fixes.  Ideally, Herbalism becomes a lifelong commitment and therefore a slow deep process.


A: The package price is for my clinical service fee. The cost of herbs and supplements is separate, as it is 100% customized to you. I will present you with an itemized list for your approval before any purchases are made. The Concierge Plus tier includes a $50 credit to get you started.


A: This is a common concern! We have many options, from tinctures and capsules to teas and powders. We will find a method that works for you. Your comfort and consistency are my top priorities.  That being said, learning to adapt our pallets is part of an herbal path and will be something that we can work together towards.
