The Science Behind Plant-Based Essential Oils and Their Healing Properties

Everyone comes home from a tiring day, waiting to relax and unwind in their bathtub. However, you find that something is missing in the mindful setting. That’s right! Scented essential oils are complex mixtures of hydrocarbons and their oxygenated derivatives derived from two different isoprenoid pathways. They have been used in many different traditional healing systems since ancient times due to their biological activities.

Preclinical studies have documented their antimicrobial, antioxidant, anti-inflammatory and anti-cancer activities in a number of cell and animal models. Plant-based extracts are found in colonizing terrestrial plant organisms and treating them with aromatic pigments and compounds. But do they work? This article will familiarize you with the science behind plant-based oils and where their healing properties expand to:

How Did Plants Evolve For Healing?


Plants have been a major food source of feed, fiber, and medicaments for humans. Essential oils are complex mixtures of hydrocarbons and oxygenated hydrocarbons arising from the isoprenoid pathways. Clinical trials are needed to ascertain the efficacy and safety of these plant products. Pigments and aromatic compounds attract pollinators, while phytoalexins are broad-spectrum antimicrobial metabolites.

The volatilization penetrates the soil, causing leaching to the atmosphere and then back to the soil. Depending on the supplier, you may have restricted varieties of plants that can produce aromatic solutions.

However, partnering with the right plant-based essential oils supplier can provide customized extracts for aromatherapy, perfumes, blends, mists, bath bombs, bug sprays, bath soaks, and other scented oils for a relaxing and healing atmosphere.

Their Role In Ecology

The precise function of the chemicals involved in PVs’ ability to modulate the interaction between abiotic and biotic factors is still unknown. Constitutive PVs (constitutive) are expressed irrespective of external stimuli and are mainly made of terpenoids plus shikimate derivatives and polyketides. They have four main functions:

  • Reducing abiotic stress
  • Allelopathy
  • Defending against herbivores
  • Inter-plant signaling
  • Defense against microbial pathogens
  • Attracting pollinators and seed dispersers
  • Inhibiting their growth through direct antibacterial, antiviral and antifungal activities

The Scientific Mechanisms Of Essential Oil


Essential extracts are a complex mixture of molecules with low molecular weight, monoterpenes and sesquiterpenes, some of which are found in low concentrations. These molecules can represent up to 70% of total oil and are responsible for their biological effects. Several extracts have been studied for their cytotoxic capacity.

The main mechanisms that mediate their effects include cell death induction by activating apoptosis and necrosis processes, cell cycle arrest, and loss of function of organelles. Some essential oils may also act as pro-oxidant elements, altering cellular redox state and compromising cellular survival. Given below are certain activities found by science in these oils:

  • Anti-Cancer Activity

Essential oils have been investigated for antioxidant and anti-inflammatory properties, undertaking their insights into inflammatory disease recovery. They have anti-cancer effects due to their relationship between reactive oxygen and inflammatory states that lead to cancer.

Overproduction of reactive oxygen species (ROS) damages DNA and increases mutation, which can be effectively tackled through the anti-cancer properties of plant-based extracts. Cancer drugs aim to induce apoptosis (cell cycle arrest) in cells. Essential oils can provide anti-profusive properties and apoptosis components like glioblastoma, melanoma, leukemia, etc. By preventing excessive generation of ROS and targeting protein kinase B, it can prevent early stages of cancer.

  • Antifungal Activity

ROS is an increasingly popular synthetic drug due to its antimicrobial properties. Several studies have demonstrated the effectiveness of extracts against fungal species. Scientists have undertaken testing several oils from aromatic plants.

These extracts include oregano, thyme, lavender, rosemary, fennel and laurel against tomato late blight disease agent. The treatment with the oils caused the loss of integrity of the cell wall and plasma membrane permeability with important morphological alterations in hyphae. Essential oils have been evidenced, which inhibited aflatoxin production.

Ergosterol is a compound of fungi that plays an important role in maintaining the integrity and function of the fungal cell. Essential oil cytotoxicity was examined against fluconazole-sensitive and-resistant isolates, and it was found to disrupt membrane integrity and inhibit ergosterol biosynthesis. In addition, ROS overproduction and oxidative stress were reported to mediate the cytotoxic effects of oils.



The science behind plant-based essential oils and their healing properties is wonderful. Science explains how plants have evolved for healing, their role in ecology, and the scientific mechanisms of oils. Essential oils also exhibit the anti-cancer and anti-fungal properties of oils and how they have been used in traditional medicine for over 5000 years.

Specific oils, such as eucalyptus and mint, have also exhibited high levels of medicinal and aromatic properties. A reliable supplier can provide various effective plant-based essential oils and their healing properties.
