Why Choose Organic and Wild Harvested Ingredients?

Organic and Wild Harvested Ingredients

Organically grown plants, including herbs, flowers, nuts and seeds have higher concentrations of beneficial antioxidants, lower concentrations of heavy metals and less pesticide residues, compared to conventionally grown plants (1-6).   


What are Pesticides? 

  • Pesticides are used to kill, repel or control certain forms of animals, plants, insects, fungi or microorganisms that are considered to be pests.

  • Pesticides include rodenticides for killing mice and other rodents, herbicides for destroying unwanted plants, insecticides for controlling a wide variety of insects, fungicides to prevent the growth of mold and disinfectants prevent the spread of bacteria (7).

Why Should I Avoid Pesticides? 

  • Pesticides are designed to cause damage to living organisms. 

  • Pesticide exposure can directly affect genetic material, causing damage to DNA and increase the risk of many different types of cancer, including prostate cancer (8), leukaemia (9) and brain cancer (10).  

  • There is a growing amount of evidence that exposure to pesticides can increases the risk of disease, including diabetes (11) and neurodegenerative disorders such as Parkinson's disease (12) and Alzheimer's disease (13).  

  • There is circumstantial evidence on the association of exposure to pesticides with respiratory problems, particularly asthma and chronic obstructive pulmonary disease (COPD), cardiovascular disease such as atherosclerosis and coronary artery disease, autoimmune diseases like systemic lupus and rheumatoid arthritis, chronic fatigue syndrome, and accelerated aging (14).


How Do I Avoid Pesticides?

  • Pesticide residues are found throughout the environment and have been detected in the urine of 70-90% of children and adults tested (15-17). 

  • In plants sprayed with pesticides, residue on peels and external bits are used to make essential oils so pesticides may become concentrated during processing.

  • The good news is that eating an organic diet for just 5-7 days has been shown to significantly reduce pesticide levels in children and adults (18-21).

  • Pesticides can also be absorbed through the skin (22-24), so you can reduce your exposure by choosing organic ingredients for your skin care, hair care and cleaning products.


We care about the health of our clients, the farmers who grow and care for the plants and the artisans who process and extract our fine plant compounds. 

We only use organic and wild ingredients in our blends to minimize exposure to harmful pesticides.
