Different Forms of Herbal MedicineInternal In Solid Form | | Tablets v Capsules For dried products the choice between capsules and tablet is often reflected by personal preference and availability. However capsules tend to be preferred by many, now that non-gelatine capsules are widely available. | | Tablets | Compressed powders or extracts, often with no additional preservatives and only natural binders. They may be coated to increase their storage life, using maize protein or vegetable cellulose. | | Capsules | Can be used to take powders and oils, and are often used to mask the smell or taste of less pleasant herbs. Capsules may be made of gelatine (animal by-product) but are also available from non-animal sources (e.g. Vegicaps). | Internal Liquids | | Juices | The liquid portion of a herb or other plant, extracted from fresh plants, often by pressure. They do not normally have additional preservatives and so should be refrigerated and drunk within the time stated on the bottle. | | Oils | Essential fatty acids can be taken in the form of capsules or as the oil. | | Floral waters | These are the residue from the production of the essential oil by distillation. They may also have the essential oil added.
Cheaper floral waters only consist of water with drops of essential oil and are not generally recommended for internal use. | | Tinctures | These are the extract of the herb in alcohol. The alcohol is able to extract non-water soluble constituents of the plant, as well as extracting the water soluble constituents at lower alcohol concentrations. The alcohol also acts as a preservative. | | Teas | Herbal teas may be made either as an infusion or a decoction. An infusion is made by placing the herb in hot water, similar to making a cup of tea. A decoction normally requires the herb to be simmered for ten to fifteen minutes. | Skin Preparations | | Creams v Ointments v Lotions v Liniments The choice between this range of products depends on personal preference, the use the product is being put to and their availability. | | Creams | Creams are a mix of water and oil. Creams are lighter than ointments and have a cooling effect. | | Ointments | Ointments are oil based, with no water added. They are solid at room temperature. Ointments are normally greasier than creams and can be used for very dry skin. They keep heat and moisture in. | | Liniment | A liniment is liquid, and is often a mix of tincture and oil. | | Lotions | Lotions are a liquid version of creams. | | Oils | Carrier (fixed) oils are vegetable oils (e.g. sweet almond oil, grapeseed oil). They may be applied directly to the skin, or used to make other preparations.
They may be infused with herbs (e.g. calendula/marigold) to make infused oils. | Others | | Essential Oils | Essential oils are extracted from plants (often by distillation) and are the volatile constituents, responsible for the smell of the plant. They should be diluted before external use; in water, in creams etc. |
Even once you have decided which form to take a herbal remedy in there are yet more choices to make.Organic v Non-OrganicOrganic herbs are grown without the use of artificial fertilisers or pesticides and are GMO (genetically modified organism) free. The grower uses other farming techniques to protect his crop. Standardised v Non-Standardised v ExtractsEach herb is made up of hundreds of chemical constituents (phytochemicals). Scientific research often indicates the medical activity of one or two of these constituents. Plants may have varying amounts of these chemical depending on the growing season, area grown and so on, therefore some manufacturers standardise their herbal products to contain a specified amount of these medically active constituents. These are standardised products. Products that do not have these constituent quantities controlled are non-standardised (the levels may be above or below the standardised product as naturally found in the plant). Many herbalists prefer this 'unadulterated' form of herb, because they believe that all of the chemical constituents in a herb work synergistically and that standardisation may upset the balance of this delicate relationship. In addition, standardisation requires further processing of the herb. Other manufacturers make extracts which only contain the one or two researched and identified medically active constituents. These extracts may represent only a small fraction of the active constituents of a herb. Other ConsiderationsThe old adage "you get what you pay for" is often overused, but in the case of herbal medicine we believe we have chosen our suppliers carefully. However we sometimes offer the same "product" from two suppliers to ensure that our customers have a choice of price ranges. Often the reason for a product being perceived as very good value is written in the small print, or even the large print. - Always look at the strength of the product you are buying. A 200mg vitamin C per tablet may be cheaper than a 1,000mg tablet, but if you have been recommended 1,000mg of vitamin C a day then 5 tablets will be needed to reach the same strength as a "more expensive" 1,000mg tablet. Similarly, a standardised extract of Xmg of hypericin (a St Johns Wort extract) may be cheaper than a standardised herbal capsule containing Xmg St Johns Wort. That is because the extract contains only one ingredient whereas the tablet contains all the other ingredients as well!.
- Herbs are grown by different methods; farms and farmers have different resources and standards. This may affect the concentration and constituents of the plant. Some of the suppliers set and maintain the standards of their producers (or produce their own) and therefore their products should be higher quality.
- Aloe vera products may claim to have "100% aloe vera" however this is often misleading as aloe vera products do not need to state how much water is in the product. So 100% aloe Vera may actually consist of 95% water and 5% aloe vera! If an aloe vera product is very cheap then ask about its constituents.
- Oils (such as the essential fatty acids) can be extracted quickly and cheaply using heat, however this degrades the product. Essential fatty acids should always be extracted using cold pressed methods and stored away from sunlight. This may explain the price difference between two "identical" products.
- Some companies invest in research and education. They are developing products for all of us, and increasing the knowledge and therefore potential safe use of supplements for all. For example, Solgar provide training for retailers to ensure good advice is given; they provide information and education leaflets for consumers; they research and develop products; as well as ensuring high quality processes and checks are in place. So although their products may appear slightly more expensive, they are delivering a far better service for the customer.
