Herbal Medicine

Upsets with emotions affect the nervous system which in turn compromises the immune system.

The planet is becoming more mineral deficient.

Naturopathy is complementary with orthodox medicine

Herba is a latin work meaning grall or herbage

Wort – early name for herbs – prized for its medicinal properties

How herbs work:-

Nutritive

Carminative

Herbal medicines are specific to an organ system

Differences between Allopathic and Complementary

Allopathic

Botanical

Inorganic

Organic

75% of them are synthetically derived so don’t have vital force

Taken exclusively from plants and limited processing so have vital force

Can’t classify as a food

Is a food as has all the nutrients and fibre of the plant

Cannot be assimilated into the body as they can’t be absorbed and the residue can be trapped between the cells

Are assimilated in inorganic matter (minerals) and contain these minerals and convert them into organic matter which can be assimilated into the body

Use isolated constituents from the plant so do not get the benefit from the other constituents of the plant

Use the total part of the plant so benefit is gained from all constituents that balance eachother in effect

Have more of a toxic effect

Work to detoxify the body

Do not have vital force

Contains vital force and enhances or supports the person’s vital force and help promote normal health

Give neither life nor strength

Provides food for tired cells at the same time as curing the disease

Does not restore tone to the organ or tissue system

Stimulates organ function by their tonifying action

Works by irritating or provoking vital centres into action

Works on the whole organ system and heals it by toning and supporting it to enhance its functioning

Treats symptomatically

Works by treating the underlying illness that is causing the symptoms

Offending organ singled out

Treats the whole organ and tissue system

Not holistic

Holistic as it treats every facet of the person

Doesn’t help the body to increase the immune system

Increases and strengthens the immune system

Glycosides

Glycoside = glycone (sugar) and aglycone (non-sugar – is the therapeutic action but needs the sugar to work)

  1. glycosides in plants are involved in protective and sanitary functions. They are located in flowers, leaves, seeds of pulses, yams and sweet potatoes.
  2. On hydrolysis they yield one or more sugars (glycone) as well as a non-sugar component (aglycone). The sugar component is given a name dependant on the type of sugar it is derived from e.g.
  1. from the aglycone one can expect to find groups from other classes of plan constituents, for example:
  1. there are several types of glysides, some of which include the following:
  1. Cardiac glycosides work on the heart by enhancing the rate and rhythm of the contraction of the heart and are used in congestive heart failure
  2. Steroidal glycosides have the ability to provide the precursors for steroid production
  1. Anthocyanadin glycosides are flavonoids structurally related to flavones. Their glycosides are known as anthocyanins (Greek – antho=flower, kyanos, blue)
  1. cyanogenetic glycosides are found in the kernels of some fruits e.g. amygdalin which is found in the bitter almond (otherwise known as Laetrile or vitamin B15) or prunasin from Prunus serotina – sedative and antispasmodic action. These constituents are highly toxic in large amounts
  1. Anthraquinone glycosides are used for the treatment of chronic constipation of the bowel
  2. Flavonoid glycosides are primarily considered to be anti-inflammatory and anti-allergy herbs as well as being useful for the treatment of capillary fragility and other blood vessels disorders.
  3. Phenolic glycosides are antiseptic, antibacterial, have an affinity with mucous membranes

 

 

Anthraquinone Glycosides:

  1. This is a term given to a group of natural purgatives or stimulant cathartics which are used for the treatment of chronic constipation.
  2. Herbs containing anthraquinone glycosides have yellow, orange-red pigments and are bitter to taste. They , therefore, stimulate bile flow. They are used as dyes in the textile industry. They are usually soluble in hot water or dilute in alcohol.
  3. The glycosides upon hydrolysis yield aglycones that are di, tri or tetrahydroxy-anthraquinones, or modifications of these compounds.
  4. The action of herbs containing anthraquinone glycosides is dependant on the presence of bile and that they are digested in the glycoside form. Bile and the glycone component of the glycoside is necessary for absorption of the anthraquinone from the gut. The aglycone has no therapeutic action on its own.
  5. Absorption takes from 8 – 14 hours before peristalsis has become enhanced sufficiently to bring about evacuation of the bowel.
  6. Stimulant cathartics work by increasing the tone of the smooth muscle wall of the colon which leads to increased contraction and peristaltic motion. They should only be used short term as over use will lead to exhaustion of the stimulated tissue and constipation will re-occur.
  7. The stronger anthraquionone glycoside herbs have a tendency to produce griping therefore carminative herbs whould be combined with these to reduce this effect. Anethum graveolens (Dill) Foeniculum vulgare (Fennel)

ALKALOIDS:

Alkaloids are derived from a diverse range of play courses including roots, rhizomes, leaves, bark, fruits and seeds. Most occur in the Leguminosae, Solanaceae and Rubiaceae family. All alkaloids end in "ine" which is a chemical rule. Some times there is a fine line between the therapeutic dose and a toxic dose

Properties:

Bitter to taste, usually alkaline and they contain one or more nitrogen atoms (e.g. Ergotamine contains 5 nitrogen atoms). Many alkaloids are the most poisonous of known substances.

Actions:

  1. Sedative – most pronounces action on the nervous system bringing about physiological or psychological changes. The alkaloid Reserpine (from Rauwolfia serpentine – Snake root – schedule 4) acts as a sedative depressing the central nervous system and is useful for psychiatric conditions such as schizophrenia, also useful for hypertension. Withania somnifera – sedative adaptogen, tonic – stress, exhaustion leading to impotence. Its high in iron, is anticancer and decreases sensitisation.
  2. Hypotensive – indicated for the treatment of hypertension e.g. Rauwolfia serpentine acts by blocking neurotransmitters which leads to dilation or relaxation of blood vessels which causes the blood pressure to drop
  3. Hypertensive – Ephedrine (Ephedra) in inappropriate doses – anti-inflammatory, allergies including asthma and hayfever.
  4. Analgesic and Narcotic – codeine and morphine (Papaver somniferum) severe pain
  5. Mydriatics – atropine (Atropa belladonna) is a muscle relaxant and dilates the pupils
  6. Bronchodilator – Lobeline (Lobelia inflata) for the treatment of asthma
  7. Antimicrobial – Berberine (Hydrastis canadensis, Berberis vulgaris) bacterial infections
  8. Antileukemic – vinblastine (Vinca rosea) oncolytic activity (contains over 90 alkaloids)
  9. Oxytocic – (Claviceps purpurea – Ergot of Rye) post partum haemorrhage
  10. Stimulant – caffeine (Cola vera)

The names of the alkaloids can be obtained in the following way:

* Generic name: Hydrastine from Hydrastis canadensis

(genus) Atropine from atropa belladonna

* Specific name: Cocaine of the plant yielding them – Coca leaf

(Erythroxyllium coca)

* Common name: Ergotamine from the plant ergot

* Physiological Activity: Emetine producing emesis (vomiting)

Scheduled herbs containing alkaloids (not for internal use):

Symphytum officinalis – comfrey (alakaloid Pyrrolizidine) causes irreversible liver

damage – can be used externally for ulcers and broken

bones

Tussilago farfara – Coltsfoot (pyrrolizidine) may be smoked for emphysema

Borago officinalis _Borage (pyrrolizidine)

Pyrrolizidine (comfrey)

 

VOLATILE OILS:

  1. Volatile oils are ‘odorous’ principles found in plants and because they evaporate when exposed to the air at ordinary room temperatures they have been given the term "essential oils". The oil may be stored in special glandular airs (labiatae), oil tubes called vittae (Umbelliferaea) and modified parenchyma cells (Piperaceae).
  2. Properties of volatile oils:
  1. are soluble in alcohol and fats
  2. slightly soluble in water
  3. most essential oils are colourless apart from Azulene which is blue (Matricaria recutita – Chamomile).
  1. extraction of oils is achieved by steam distillation which is the most common method of extraction. Other methods include solvent extraction, infusion, and water distillation
  2. Pathway of volatile oils:
  1. The total volume of essential oil of the plan it generally very low from 1 – 5% or more. Many therapeutic oils are so potent they are still active in the Galenic preparation. On isolation they are highly concentrated and widely used as oils for aromatherapy where they are diluted in a carrier oil.
  2. Volatile oil compounds are a mixture of hydrocarbons with Terpene being the most common type which is built up from the isoprene molecule (C5H8). A variety of substances can be synthesized by starting with this molecule as a building block. Starting with the simplest substance we have the following variations:
  1. monoperpenes - C10H16
  2. sesquiterpenes – C15H24
  3. diterpenes – C20H32
  4. sestertepenes – C25H40
  5. triterpenes – C30H48

Monoterpenes:

Carvone (dill and caraway) }

Menthol (peppermint) }antiseptic, useful for sore throats/infections of the

Thynol (thyme, catmint) }mucous membranes

Thugone (sage) }

Citral (lemon balm) }sedative or carminative, good for nervous exciteability

Linonene (fennel, dill and caraway) }headaches and paliptations

Camphor (catmint, rosemary, sage) }circulatory stimulant, digestive stimulant, relaxes

}cardiac sphincter

diosphenol - (diuretic) (buchu)

Sesquiterpenes:

Azulene (blue chamomile) – anti inflammatory and antispasmodic

Bisabolol (blue chamomile) – anti inflammatory

Actions of volatile oils:

  1. carminative
  2. antiseptic
  3. antispasmodic
  4. bitter
  5. peripheral vasodilators and/or circulatory stimulants
  6. relaxant and sedative

Flavonoid Glycosides

Flavonoid is derived from the Greek work ‘flavus’ for yellow. (flavonoids which are coloured red, blue or violet are called Anthocyanins)

  1. Flavonoids are glycosides which can be broken down into four main groups based on the ‘flavone’ model
  1. Flavones and isoflavones (the latter are isomers of flavones)
  2. Flavonols
  3. Isoflavones
  4. Xanthones

properties of flavonoid glycosides are as follows:

  1. taste is bitter or sweet
  2. isoflavones have steroidal properties (genistein found in trifolium is oestrogenic and is good for breast tumours – binds to receptors)

actions of flavonoid glycosides

  1. anti-inflammatory
  2. anti-allergic
  3. decrease capillary fragility and permeability of blood vessels
  4. cardiac regulating
  5. immunostimulating
  6. anti-oxidant
  7. diuretic
  1. anti-inflammatory and anti-allergic
  1. capillary fragility and permeability of blood vessels
  1. cardiac regulating
  1. immunostimulating
  1. anti-oxidant
  1. diuretic action

 

Tannins

  1. Tannins represent the largest group of polyphenols (number of phenolic groups)
  2. They are usually found in volume in the outer cork and heart wood of the Oak tree (quercus species) also old and drying leaves, the bark and the richest source of all being insect galls of the oak tree.
  1. Properties of tannins are as follows:
  1. taste is sour
  2. they form precipitates with protein, heavy metals, alkaloids and especially with gelatine and salivary proteins
  3. due to the preciptation of proteins, tannins have the potential to inhibit enzymes and bacteria
  4. much of the tannin remains unabsorbed in the gut after ingestion and a variable amount makes its way through the body fluids as tannate where it is then excreted by the kidneys
  1. there are two types of tannins:-
  1. condensed tannins
  2. hydrolysable tannins
  1. tannins are considered to be astringent in action which occurs in the following way:
  1. drying
  2. contracting or binding
  3. Haemostatic
  4. Strengthening

 

  1. drying
  1. binding or contracting
  1. haemostatic

 

  1. Strengthening
  1. Cautions and contra-indications
  1. to be used short term as long term use can lead to reduced absorption of nutrients across the gut wall lining due to thickening or hardening of the mucous membrane lining
  2. long term use can lead to the development of constipation as tannins are drying
  3. are contra-indicated if chronic constipation is an existing problem

 

Saponins – Steroidal Glycosides

1.Characteristics

  1. Saponins are derived from the Greek work "Sapo" for soap
  2. they are complex glycosides and when combined with water forms a colloidal substance which, when shaken, forms a lather e.g. Saponaria officinalis (Soapwort) which is used exernally for the treatment of dandruff

2. Properties

  1. Haemolytic – ‘dissolves’ the cell wall of the red blood cell and disrupts them when injected intravenously and are therefore considered to be toxic if used this way. Can be said to increase permeability of membranes
  2. When taken orally saponins are considered to be harmless and they accelerate the body’s ability to absorb other active compounds such as minerals for example
  1. On hydrolysis the glycoside splits into a sugar + sapogenin (aglycone) the sapogenin does not have haemolytic properties
  2. Saponins fall into two types of steroidal glycosides:-
  1. triterpenoid (pentacyclic triterpenoids)
  2. Steroidal (tetracyclic triterpenoids) are less widely distributed than the triterpenoidtype
  1. Saponins have the following actions:
  1. anti–inflammatory expectorant (stimulant type)
  2. diuretic
  3. hormonal as previously mentioned
  4. antispasmodic
  1. Anti-inflammatory
  1. Expectorant (stimulant type)
  1. diuretic
  1. hormonal (steroidal)
  1. Antispasmodic

Herbal therapeutics

  1. The therapeutic dose is to be observed at all times. That also includes all cautions and contraindications for each herb
  2. The following observations should always be taken into account
  1. is the condition acute of chronic as that will determine the treatment
  2. is the medicine for an adult or a child
  3. is the patient weak or strong (physically and emotionally)

NB after starting on a herbal remedy, if a person starts to show symptoms such as dizziness then they are possibly reacting to the herbs. If this is the case you can either lower the dose, change the herb or change to homeopathy

NB with people who have ADD you can use herbs to calm down their nervous system then take out of their diet all the foods that cause problems such as sugar. Their blood sugar level usually needs balancing

NB the contraceptive pill can cause polycystic ovaries and endometriosis

NB cod liver oil is good on women who have beards

NB red raspberry leaf tones the uterus

  1. Pregnancy and lactation
  1. do not use any herbs during the first trimester
  2. there are some herbs that are safe – use only the mild and nutritive herbs
  3. be aware of those herbs that are contraindicated during pregnancy (such as senna) and avoid using them
  4. the doseage prescribed is to be much lower than that usually prescribed for a woman (e.g. 10-30 drops t.d.s.)
  5. avoid any herbs which have an action on any organ in the pelvic region (e.g. anthrocyanine glycosides, emolient enagogues which normalise the menstrual cycle and cause bleeding)
  6. if the woman is constipated may use psyllium hulls, increase her fresh water intake, fresh fruit and vegetables, magnesium and calcium
  1. Age will determine the doseage expecially for the young and elderly who take a similar dose to the young e.g. 5 – 10 drops for people 7 –10 years and for elderly people.

- Young’s Rule child’s age + 1

      1. age

- Cowling’s Rule Age of next birthday + 24

i.e. if the child is 3:

Young’s – 3/12 + 1/3 = ¼ + 1/3 = 1/7

Cowling’s – 4/24 = 1/6

If the adult dose is 1 – 2 mls (20 drops to a ml)

1 – 2 % 20 = 20 – 40

1/7 = 3 – 6 drops

1/6 = 3 – 7 drops

  1. Gender
  1. Generally women require lower doses due to average lower weight and size
  2. Hormonal status will determine wome herbs that will need to be avoided especially in women who have problems with their oestrogen/progesterone ratio

NB if oestrogen is high avoid herbs such as licorice and fenugreek

NB fenugreek in the middle east is given to women to increase their milk production. Can also increase breastsize in women but can cause oedema

NB red clover – phytoestrogen wild yam – progesterogenic

  1. Doseage

NB Pulsatilla changes the baby’s position in the uteris.

Prinicples to be applied for oral administration of herbs.

  1. slow and gradual effect – take medicine in a small volume of syrup and milk in between meals to decrease its absorption rate
  2. to achieve a local effect on the stomach or intestinal lining medicine may be taken in Acacia gum or olive oil to decrease absorption rate
  3. bitter tonic herbs are best taken 30 minutes before a meal to increase appetite/digestion
  4. for irritating medicines prescribe them in milk or syrup or combine them with protein food to prevent irritation from happening
  5. where there is hyperacidity of the stomach prescribe medicine after a meal to neutralize the digestive juices
  6. NB if cleansing 1.5 – 2 hours between meals if quick absorption into the blood is required

  7. to aide absorption of herbal medicines such as for alterative hormones or to produce a rapid effect, best taken 1 – 2 hours before or after a meal
  8. if any nausea or vomiting is experienced medicine may be taken in a large volume of fluid, syrup or honey. Check the person’s liver function as well

NB to slowly cleanse liver – increase amount daily of raw food, fish. Decrease red meat intake to twice a week. Do not have any dairy and decrease carbohydrates

NB gradual weight loss is permanent

NB the first month of any new regime is the hardest. After than, if continued, becomes a permanent regime in the person’s body and mind

NB tinned fish is as good as fresh

NB easily tolerated fruits include peaches, pears, dark grapes, mandarins, blueberries, bananas and apricots

NB if the person complains of bloating then they possibly have a salicilate intolerance

NB decrease dairy intake – maximum of 3 times a week and only 30 grams

NB if parents have an intolerance then their children will probably have the same intolerance

NB Hyvitas – great vitamin formula for kids

Treatment of Acute Diseases

Treatment

NB always be careful with tannins.
