Summer is Here! So are the Insects! What Choices Do We Have Using Essential Oils?

The Larvicidal Activity of some Essential Oils –

Did you know that some Essential oils have larvicidal activity?

Larvicidal activity is an insecticide designed to kill larval pests. That means it can be used to literaly kill the larvae of the mosquito too. This is really cool when one thinks that some essential oils can be used for this purpose.

For example Ajowan (Trachyspermum ammi) and Peru balsam (Myroxylon pereira) oils can be used to treat and eliminate the mosquito larvae with an enviable efficiency 97.5% (S1)

Ajwain or Ajowan (https://en.wikipedia.org/wiki/Ajwain) is a plant used as a spice mostly in the Indian cuisine: deliciously blending it with green beans and root vegetables or steamed cabbage. Research into the properties of the essential oil extracted from this interesting spice shows that its components (Thymol, phenolic compounds) are strongly germicide and antispasmodic (S2).

In the table below are some oils that can be used safely for the purpose described above.

Above all, keep safe, cool and have a great a great Christmas.

Allergies Seasonal Allergies – What can Essential Oils Do for YOU

Are you suffering from occasional allergies in spring or early summer?

Read this first:

There are risks and potential complications of using essential oils: this is particularly true for allergic prone people

  1. Pain, swelling, or tenderness of the skin;
  2. Itchiness;
  3. Hives, rash, or boils;
  4. Digestive upset;
  5. Difficulty breathing.

Essential oils can be used as an alternative or complementary treatment for allergy symptoms.

Before using the Essential oils BIBI Therapy always conducts an Allergy test reaction. Apply a small dose of essential oil (1–2 drops) diluted in 3–6 drops of carrier oil and apply to an inconspicuous area of skin (such as the abdomen, thigh, inner arm, etc.).

Allow the oil to fully absorb into your skin and then examine the area over the course of several hours. If any redness, pain, itchiness, swelling, or other adverse symptoms result, you may have sensitivity to that oil.

Aromatherapy can be used in various ways to assist you with this ailment:

  • diffusing them into the air;
  • using them in bath and spa products;
  • applying them onto the skin ( diluted);
  • or breathing them directly from a nasal container.
