Adaptogen An agent that reduces reactions to various stressors, therefore helping to restore and maintain a normal balance to the body.
Agonists A plant compound which binds to a receptor and activates it, producing a pharmacological response (eg contraction, relaxation, secretion, enzyme activation, etc).
Alkaloids A naturally occurring organic compound containing nitrogen. Many alkaloids are physiologically active and can be used in small quantities as medicines, but if taken in larger doses they can be extremely poisonous. Examples include caffeine and nicotine.
Antangonists A chemical that, when bound to a receptor, blocks the receptor and prevents it from responding. Antagonists prevent agonists from binding or attaching to the receptor, inhibiting the physiological action of that receptor. Antagonists include caffeine and naloxone.
Antioxidant A chemical that prevents oxidation, and subsequent production of "free-radicals" which are harmful to the body.
Anxiolytic An anxiety-reducing agent.

Decoctions The liquid resulting from extracting the essence of a substance by heating or boiling. This tea preparation method is used for the more robust/woody parts of the plant such as root, stem, seed or fruit. The reason for the added cooking time is that these tougher plant parts need a longer cooking time to release the potential healing benefits.
Density The measure of how much mass is contained in a given unit volume.
Double-blind A study in which neither the study subjects (participants) nor the experimenters (researchers) know which treatment or intervention any particular participant is receiving during the study. This produces objective results without bias.

Hypokalmeia Deficiency or lower than normal levels of potassium in the bloodstream. Can cause dysfunction of the nerve and muscle cells, particularly heart muscle cells.
Hypotension Blood pressure that is below normal.

Infusions An herbal infusion is a strong tea used as a remedy, made using hot or boiling water and steeping the plant material for a set amount of time. Infusions are the most common type of herbal tea and they're the simplest to make. Typically, infusions are made from the more fragile plant parts such as the leaves, flowers and other non-woody parts of the herb. The therapeutic effect from many of these herbs is due to the volatile compounds and it is important not to boil these herbs so that these delicate compounds are retained.
In-Vitro Literally translates as "in glass." An artificial environment created outside a living organism (eg a test tube or culture plate) used in experimental research to study a disease or process.
Irradiated A plant material that has been treated using gamma-rays. This is a sterilization method against microbial deterioration and insect infestation during storage and transport. Irradiation is not allowed for organic ingredients. Oregon’s Wild Harvest products are all non-irradiated.

Traditional Chinese Medicine (TCM) A holistic practice based on a concept of balanced qi (pronounced "chee"), or vital energy, that is believed to flow throughout the body. Disease is proposed to result from the flow of qi being disrupted and yin-and-yang becoming imbalanced. Among the components of TCM are herbal and nutritional therapy, restorative physical exercises, meditation, acupuncture and remedial massage.
