After 6 years of talking about integrative health on YouTube, with +76,000 subscribers, nearly 500 videos published, and 5 million views, I still get asked the same question:

"Which oil will help me with disease X?"

That's why I wrote this book.

Because if you don't figure out where the problem is coming from, dousing yourself in essential oils, herbs and supplements won't really help you.

Who is this book for?

One of the first readers declared:

I have loved reading this book! It is personable, inspiring, and relatable. It provided me with effective tools to improve my wellbeing. I loved her personal experiences and the richness of the content she provides! I would recommend this book to anyone who wishes to undertake the rewarding path of a more intentional living and perhaps is unsure about where to start.
Tisha’s approach is the perfect mix of knowledgeable and tested scientific research with a refreshing spin on mindset, nutrition and emotional well-being.
I sure hope this is the first of many other writings based on her precious lifelong studies and experiences with wellness!

Important Note

The content of this book is not intended to replace the advice of specialized medical or health professionals.

I'm not going to recommend that you stop taking medication or do anything crazy.

I want to empower you to truly understand why you got sick and take practical steps to make root changes, as well as apply solutions to improve your situation, using the most useful tools (some of which may be medical).

I am a health coach, not a doctor, and I am not here to cure you.

I am here to uncover some of the mysteries of health and help you heal yourself.


If you want to throw your problems at someone else and not take responsibility for your life; if you're looking for easy and quick solutions that allow you to keep doing all those things that are really harming you, then this book is not for you. Because I'm going to empower you to ACT, and if you're afraid to act or just want someone to rescue you, this is not what you're looking for. Frankly, that attitude doesn't work, so think about it and if you dare to start this detective work with me, I promise it will be inspiring and you will finally be able to take control of your life.

A bit of my story



I'm Tisha Klemetz, an integrative health coach and a "hospital old-timer".

In 1982, doctors diagnosed me with the worst type of cystic fibrosis and said that I wouldn't live beyond the age of 5. Obviously, we managed to avoid that.

I have been taking health courses all my life, accompanying my mother to the courses she took, since I was 6 years old. This book is a summary of what I have learned and is also a deepening of everything I have been sharing on YouTube (in Spanish).

Some reviews

An ideal guide in which step by step and concisely, we learn to become more aware of ourselves and to find out how we are feeling in order to take care of ourselves in a more proactive way. In short, how to take control of your health so that it is much more difficult to become ill.

Frequently asked questions (FAQs)

Is this what you have on YouTube?

No. Although I have touched on some of these topics briefly, much of what I have in the book are things I have never said in public videos. In book format, you also have it in a well-structured context. The experience of consuming information in writing is quite different from watching it in videos, in any case.

Is this a book about essential oils?

I mention some essential oils but only as part of the overall strategy. This book goes beyond that, investigating the roots of diseases and various strategies or tools that you can use to manage them.

Are there any shipping costs?

No, it's much better because you have immediate access. You can download a PDF file and read it on your phone, tablet, or computer. In case you have an e-book reader (such as Kindle) or use an iPad, I also provide it in ePub format so that you can adjust the font type as you prefer. I also present it in 'flipbook' format so that you don't have to download the file at all and can read it from your browser (Google Chrome, Safari, Explorer, etc.) by flipping the pages.

How much does it cost in my country?

The price is in US dollars. When you pay, it will be automatically converted to the currency of your country.

How do I pay for it?

You can pay with a card (debit or credit) or with PayPal.
