Aromatherapy Explained


NZROHA is an organisation that is promoting professional Clinical/Holistic Aromatherapy or Aromatic Medicine safe use.

Aromatherapy is the use of essential oils to enhance physical and emotional well being. It is the fastest growing natural therapy at this time, attracting media attention and becoming highly popular with many people. A multifaceted healing modality Aromatherapy use includes:

  • Inhalation & vaporisation
  • Compresses
  • Bath or shower
  • Massage
  • Spritzer sprays
  • Skin care
  • Household cleaners
  • Deodorisers
  • Insect repellent
  • Mood enhancer

Aromatherapy can be fast acting but it is not a 'magic potion.' Your individual blend or 'mixture' of essential oils will not only provide immediate benefits the lasting effects will continue to be felt for sometime after the treatment.

A registered Aromatherapist will compile a case history and at each consultation will review your current symptoms and formulate a blend that is appropriate for you at that time. You may be given a cream or blend to use between visits to enhance the healing process.


Essential Oils


Essential oils are the 'life force' of the plant from which they are extracted, usually by distillation. They have individual chemical constituents which give them unique therapeutic properties.

Essential oils have many healing properties to assist with promoting total holistic wellbeing. An imbalanced state is the surest way of developing disease.

Essential Oil Safety

  • Essential oils are 70 times more potent than the herb and caution is advised at all times. A good rule of thumb is 'less is more."
  • Use only 100% pure essential oils sourced from a reputable supplier. Some essential oils have been 'adulterated' or contaminated with poor quality oils. 
  • Note 'fragrant oils' have no therapeutic properties these are not used in Aromatherapy.
  • Oils should always be stored away from children, and should not be taken internally.
  • Essential oils should be stored in dark glass bottles, and definitely not in plastic.
  • Care needs to be taken when using any essential oils particularly for babies, children, elderly, or during pregnancy. If in doubt consult a NZROHA Registered Professional Aromatherapist.
  • It is not recommended to apply undiluted essential oils to the body. They should always be diluted in a carrier oil. 
  • When bathing with essential oils it is recommended to add a fat soluble carrier i.e. almond, or olive oil or a few tablespoons of full fat milk to help disperse the oil in the water. Use a maximum of 6 - 8 drops and care needs to be taken when selecting oils for bath use.

The fragrance always stays in the hand that gives the rose

Our Beginnings

The Register was initially formed in 1993 by a small group of enthusiastic Aromatherapists who began meeting in each other's homes as a discussion and support group. They agreed that they needed a nationwide register of Holistic Aromatherapists. In January 1993, together with 8 other Aromatherapists, Sue Waddell and Helen Guthrie sent out invitations to as many Aromatherapists as they could locate.

A journal ( Sharing Aromatherapy) was started, and at the same time the Register was being formed. It was incorporated on 1 September 1993 and as of 20 September, there were already 55 members through out New Zealand. We now have international memberships and have formed valuable links with overseas aromatherapy registers, such as IFA in Australia.

NZROHA has established itself as the national register for qualified Holistic Aromatherapists, supporting, informing and promoting Aromatherapy in NZ. It is a founding member of the NZ Charter of Health Practitioners Inc and is developing affiliates with other Natural Health Modalities.

The Register consists of members each being engaged, trained, or interested in Aromatherapy, or others interested in furthering the objects of the Register. The Register sets professional standards for practicing members - all members are must comply with and uphold the NZROHA Rules, Membership Policy, Codes of Ethics, and Code of Practice.

NZROHA Executive Committee meets regularly ensuring the Register is conducting itself in accordance with acts and requirements of the Register.

In June the Annual General Meeting is held in conjunction with the Conference. Ordinary General Meetings can be called at the discretion of the Chairperson to inform and discuss current issues with members. Sharing Aromatherapy is our quarterly journal packed with interesting information and available to members and subscribers.
