Elderberry (Sambucus nigra)

Elder leaves and berries

What is Elderberry?

Elder is an invasive tree spread throughout most of the world.

It can be found in cold climates like Canada and Scandinavian countries, as well as tropical areas in Central and South America, Southeast Asia, and Australia.

Elder trees are even frequently found in remote areas like the Pacific Islands.

Elder has many uses, especially for upper respiratory infections for its antitussive and antiviral activity.

As an antiviral, it has a relatively narrow range of efficacy, which is specific to enveloped viruses like influenza, and will only have a potent effect in the early stages of viral infection. Elder is highly effective for early-stage viral infection and one of the best herbs to keep around in in the event of early signs of cold or flu.

What is Elder Used For?

Elder is primarily used in the acute stage of respiratory infections. it has the unique ability to structurally inhibit the reproductive cycle of the influenza virus. If used in the early stages of infection elder can be used to prevent widespread infection.

elder is also used for its ability to interact with the central nervous system. For this effect, elder is often used for nerve-related pain.

Traditional Uses of Elder

The use of elder dates back a very long time. Evidence of elder seeds, pollen, and dried fruits have been found at a Bronze Age archaeological site in Tuscany (Italy) [12], a Neolithic site in the French Alps [13], and Durankulak site the Black Sea coast and north-eastern Bulgaria [13].

Elder is used in Ayurvedic medicine, but not in depth. Its berries are used primarily as a diuretic, and aperient, while the bark as a hydragogue, cathartic and anti-epileptic.

In traditional Chinese medicine, elder is known as "mao gu xiao" (Sambucus formosana or Sambucus chinensis) is used (rarely) to treat liver disease. It's considered to be a warm bitter, useful for dispelling blood stasis.

In Indonesia, elder (Sambucus javanica) is used for pain relief, beri beri, and jaundice.

In Western herbal medicine, elder is most commonly used to treat sore throats, and as a purgative or emetic. It's also used to treat wounds (the leaves mainly), or as a diuretic (whole plant).

Elder was commonly combined with herbs like yarrow or boneset in the treatmeent of cold and flu.

Botanical Information:

There are about 30 different species of elder, 3 of which are most commonly used as medicine. The common names for these species include blue elder (Sambucus nigra), red elder (Sambucus racemosa), and white elder (Sambucus australasica).

 

Phytochemistry

+ Constituent Breakdown:

Elder contains several hundred compounds.

This includes phosphorous (high), vitamins A, B6, and C.

Also contained are polyphenols, anthocyanins (blue-berries)(cyanidin 3-glucoside, cyanidin-3-sambubioside, cyanidin-3, 5-diglucoside, and cyanidin-3-sambubioside-5-glucoside), anthoxanthins (white berries), ribosome-inactivating proteins (RIPs) (TYPE 2 RIPs; nigrin b, basic nigrin b, SNA, SNA1, and SNLRP, nigrin f, nigrin s, ebulin 1, ebulin r1, ebulin r2. TYPE 1 RIPs; ebulitins), flavonol glycosides (quercetin-3-O-rutinoside, kaempferol-3-O-rutinoside and isorhamnetin-3-O-rutinoside (about 90% of the total flavonoid content)), phenolic acids (5-O-cafeoylquinic acid and 1,5-di-O-caVeoylquinic acid (about 70% of the total phenolic acid content)), triterpenoids (ursolic acid),

Key Compounds Found in Elder:

Chemical class Chemical Name Pharmacology
Flavonoid pigments Anthocyanins (S. nigra/canadensis) and anthoxanthins (S. australasica) Water soluble flavonoids that are absorbed through the small intestine and reach peak concentration systemically after 30-60 minutes. They Remain mostly un metabolised before being excreted in the urine.
Flavonol glycosides quercetin-3-O-rutinoside, kaempferol-3-O-rutinoside and isorhamnetin-3-O-rutinoside (about 90% of the total flavonoid content) Some have been found to bind to viral membranes, possibly delivering main mechanism of actions through hemagglutinin, M2 ion channel, and neuraminidase inhibition.
Phenolic acids 5-O-caVeoylquinic acid and 1,5-di-O-caVeoylquinic acid (about 70% of the total phenolic acid content). Caffeoylquinic acids are mainly found in the plasma and urine as hydroxycinnamate metabolites. Research has suggested that most of the absorption is done in the upper GIT. Peak concentration varies greatly, ranging from 30 min to 6 hours (Tmax).
Triterpenes Ursolic acid Downregulates MMP-9 and inhibits COX-2. Reach peak concentration in the blood after 1 hour. Half life is 4 hours.
Lignans Nigrin b, basic nigrin b, SNA, SNA1, and SNLRP, nigrin f, nigrin s, ebulin 1, ebulin r1, ebulin r2 (type 2 RIPs). ebulitins (Type 1 RIP) RIPs have been shown to bind to viral envelop proteins, and have shown activity on sialic acid in the GIT (not confirmed in the repiratory epithelial tissue). The pharmacokinetics are not well understood.

What's The Deal With Elders Toxicity Claims?

A group of compounds found in elder called lectins are closely related to the common rat poison — ricin.

Leptins are essentially proteins that can bind with sugars. If leptins like ricin get into the cells, they can interact with our ribosomes (the organelle that does most of the manufacturing of proteins and various other compounds).

The common name given to leptins like ricin that stop the ribosomes from working is referred to as "Ribosome-Inactivating Proteins" or RIPs for short.

RIPs are also thought to be protective against viruses and predators, as well as a way for the plant to store nitrogen.

Several RIPs have been isolated from black elder [18-20].

Similar lectin-compounds can be found in other medicinal plants with similar uses (antiviral), and limitations (emetic) — Phytolacca americana (Phytolacca antiviral protein or PAP).

There are three types of RIPs: Type 1, type 2, and type 3. [19, 20].

Both ebulin and ricin are type two RIPs.

How Elder Leptins Are Different Than Ricin

Despite structural similarities, elder isn't as toxic as ricin — and it's not as toxic as we once thought.

The Ld50 of ebulin 1 was 250 mg/kg, compared to ricins 0.023 µg/kg (intraperitoneal) and 0.0075 µg/kg (intravenous) [22] — that's a huge difference. You would essentially need more than 9000 times the dose of ebulin 1 compared to ricin to reach the same toxic dose.

There are some exceptions.

RIPs such as ebulin f and SELfd are toxic and resist breakdown in the stomach — leading to gastrointestinal irritation and upset.

The solution to this problem is to heat it before using it. The heat breaks reverse the ability for these RIPs to be broken down by pepsin in the stomach — thus preventing the toxic side-effects of ebulin f. [21, 25].

Clinical Applications Of Elder:

Elder is a great antiviral herb, especially for Influenza and some of the other enveloped viral species if used at the early stages of infection.

 

Cautions:

Elder is an emetic, especially in preparations that contain fresh plant material (unheated). If nausea occurs, dial back the dose. Contrary to popular belief elder is NOT poisonous. Emetics are frequently misinterpreted to be dangerously poisonous.

Elder is thought to decrease the effectiveness of morphine.

+ Contraindications

  • Small children
  • Caution advised with larger doses

Manuka (Leptospermum scoparium)

manuka-Leptospermum-scoparium-cover.jpg

What is Manuka?

In New Zealand, where manuka trees grow, the Maori consider male tea tree plants "Kanuka" and the female plants "Manuka". The plant is regarded very highly in this culture as a medicinal species.

The most well-known form of manuka is in manuka honey. This is a honey made by bees feasting primarily on manuka bushes. The honey has an impressive antibacterial profile when made from these plants. This is also reflected in the herb itself, which has been shown to have potent antibacterial, anti-fungal, and antiviral activity.

Most of the medicinal benefits of the plant come from its essential oil content, which can vary a lot depending on the region the plant was grown in.

 

What is Manuka Used For?

Internally, manuka is used to treat gastrointestinal conditions like diarrhea, colic, inflammatory bowel syndrome, and dysentery. It's also used for urinary tract infection, anxiety, and cold/flu infections.

Manuka is used topically for its antibacterial, and vulnerary actions. It's used to treat slow healing skin and bone injuries, bacterial infections, candida, and eczema. It can be gargled for gingivitis, or for general oral hygiene.

Manuka honey is another common form of the plant. It's become so popular worldwide, it's been standardised by the phenol content. This is expressed as a unique manuka factor (UMF) value set by the Active Manuka Honey Association (AMHA). Anything over UMF 5 is considered strong enough to kill MRSA.

Mullein (Verbascum thapsus)

mullein-verbascum-thapsus-cover.jpg

Mullein

Mullein is considered a staple in herbal medicine. It wasn't native to North America and was brought over by European settlers. Despite the new introduction of the herb, it was quickly adopted into use by the local native Americans and is even referred to commonly as Indian Tobacco.

Mullein is a very safe herb and offers benefits to a number of different systems in the body.

Out of all systems, mullein is most commonly used for respiratory and digestive system conditions. It's popular as an anti-catarrhal and for both soothing dry coughs, and eliminating catarrh with productive coughs. Although the entire plant can be used for either one, the leaves are generally preferred for dry coughs and the roots for productive coughs.

Mullein is as useful topically as it is internally for inflammation, muscle spasms, and infection.

 

What Is Mullein Used For?

Mullein is mainly used for treating respiratory infections and persistent coughs. Somewhat ironically, it's often smoked for its soothing effect on the lungs. It tends to increase moisture in the lungs, especially the leaves, making it especially useful for unproductive, dry coughs.

It's also used for gastrointestinal inflammation, parasitic infection, and muscle aches. It tends to have a humidifying effect throughout the body, providing a soothing effect, especially with dryness.

One of the most well-known uses for the herb is in the form of an infused oil for ear infections.

 

Herb Details: Mullein

Botanical Information

Mullein belongs to the figwort family (Scrophulariaceae) — a family consisting or roughly 65 different genera and 1800 species.

The Verbascum genus itself contains around 250 different species.

Verbascum is a popular garden plant for its ability to thrive in dry, nutrient-poor soils, and for their incredibly long flower duration.

The herb is biennial — the first season growing in a rosette leaf pattern, the second with a large velvety flower spike. Some mullein plants can grow up to three meters tall.

 

Clinical Applications Of Mullein:

Although there are many ways to use mullein, it excels with treating respiratory tract conditions. The leaves are excellent for treating dry coughs, while the root is much better for productive wet coughs.

Mullein is useful as a topical treatment for skin irritations, and as an oil for ear infections, especially the more drying flower of the plant.

Mullein also makes for an excellent lymphatic, both internally and externally.

 

Cautions:

Caution advised when working with the fresh leaf of this plant, as it can cause contact dermatitis in some individuals.

Graviola (Annona muricata)

graviola-cover.jpg

What is Graviola?

Graviola is a large tropical tree with a rich history of traditional use for conditions like cancer, parasitic infection, insomnia, and dysentery. Modern use remains very similar, mainly focusing on tension headaches and muscle aches, insomnia, diabetes, cancer, hypertension, and parasitic infection.

Although the entire plant has been used as medicine by various traditional medical systems, the most common form the plant is available in today is as a leaf extract, and raw leaves intended for tea.

Graviola is gaining in popularity outside worldwide as a general health supplement, blood sugar regulator, and anticancer agent. As a result, it's getting easier to find the herb as time goes on. It is likely this tea will become a staple in Western herbal medicine in the coming years.

Featured Graviola

 

How Is Graviola Used?

Graviola is mainly used as an adjunctive treatment for cancer, especially leukemia and other haematological cancers, as well as prostate, colon, and breast cancers.

Graviola is also popular as an anti-diabetic herb, and can be used to reduce hypertension, especially in combination with diabetes or metabolic syndrome.

Graviola is a potent anti-parasitic, useful for a wide range of different parasitic species, including worms, protozoa, and bacterial parasites.

 

Traditional Uses of Graviola

+ South America

Graviola originated from South America and/or the Carribean. All parts of the plant were used as medicine for a wide range of conditions.

The most common use of the plant appears to involve cancer treatment and parasitic infection.

The darkest leaves on the plants were used primarily as a sedative or antispasmodic. They were used to treat insomnia, arthritic pains, colic, dysentery, muscle aches, headaches, and diabetes. The leaves were often placed inside a pillow or bedsheets to improve sleep.

In Brazil, the leaves were made into a tea for treating various liver conditions. The oil of the leaves and unripe fruits were used topically for treating neuralgia, and arthritis.

In Peru, the leaves were used to treat excess catarrh, and the bark and root were used for treating diabetes, insomnia, and muscle aches.

In Guyana, the leaves were used as a heart tonic.

+ Southeast Asia

In Southeast Asia, graviola was an important treatment for malaria. It was made into candies, ice cream, and syrups for treating malaria and other parasites.
