Can you touch a horse chestnut?
The bottom line. All parts of the horse chestnut tree are toxic, but the greatest concern is for horse chestnut seeds. Similarly, horse chestnut seed extract is rich in aescin, a saponin with venotonic and anti-inflammatory properties that promote vascular tone and diminish venous congestion, leading to reduced swelling and discomfort in patients with venous insufficiency and hemorrhoids [4].Horse chestnut seed is used for diarrhea, fever, and enlarged prostate. Horse chestnut seeds can be processed so that the active chemicals are separated out and concentrated. The resulting “extract” is used for treating a blood circulation problem called chronic venous insufficiency.Horse chestnuts contain a toxin called saponin aesculin. This is in all parts of the tree but especially in the seeds. It generally produces mild to moderate symptoms but there are reports of more severe reactions.This toxin may increase the risk of bleeding due to its ability to prevent blood clots from forming. The unprocessed seeds are poisonous, and symptoms associated with horse chestnut seed poisoning include vomiting, diarrhea, headache, confusion, weakness, muscle twitching, poor coordination, coma, and paralysis.
How poisonous are horse chestnuts to dogs?
They contain a poison called aesculin, which is found in all parts of the horse chestnut tree, including the leaves. Dogs normally need to ingest several to suffer severe poisoning. Our emergency vets regularly see cases of conker poisoning in dogs in autumn. While serious cases are rare, they do occur. Today, horse chestnut seed extract is promoted for chronic venous insufficiency (CVI; poor blood flow in the veins of the legs, which may lead to leg pain, swelling, itchiness, and other symptoms), irritable bowel syndrome, male infertility, and other conditions.horse chestnut extract is commonly used to support healthy venous circulation. It is believed to strengthen the walls of blood vessels and reduce their permeability, potentially improving blood flow and reducing symptoms associated with venous insufficiency.The seeds of the horse chestnut tree (also known as conkers) have a long history of use for the symptoms of varicose veins. They act as an astringent to tighten and tone veins. They also act as an anti-inflammatory, improve blood flow back to the heart, and can reduce leakiness of capillaries and tissue swelling.Chestnuts may cause allergic reactions (hives, itching, swelling), digestive issues from high fiber content (gas, bloating), and serious toxicity if horse chestnuts are consumed raw. Horse chestnut extracts used for varicose veins may cause dizziness, headaches, and gastrointestinal upset.
Is horse chestnut safe?
The raw seeds, bark, flowers, and leaves of horse chestnut are unsafe when used orally because they contain a toxic component. Standardized horse chestnut seed extracts, from which this component has been removed, are likely safe for short-term use and have been used safely in research studies for up to 12 weeks. The seed of the horse chestnut tree is used to produce 20% aescin which is used primarily for its venotonic effect for vascular protection and anti-inflammation. It is not known for use with any male erectile dysfunction or human circulatory disorders.Raw chestnuts are safe to eat for most people. However, they do contain tannic acid, which means they could cause stomach irritation, nausea, or liver damage if you have liver disease or experience a lot of kidney problems.While they are not suitable for consumption, these nuts have high levels of saponins, which are natural compounds with detergent-like properties. This makes horse chestnuts a fantastic ingredient for homemade soap.Horse chestnut is commonly available as a standardized seed extract in the form of capsules, tablets, topical creams/gels, and liquid extracts. Most of the evidence supports using oral capsule formulations containing 16% to 20% of aescin (its main active ingredient).
How much horse chestnut per day is safe?
The most common dosage of horse chestnut is 300 mg twice daily, standardized to contain 50 mg aescin per dose, for a total daily dose of 100 mg aescin. Horse chestnut preparations should certify that a toxic constituent called esculin has been removed. Taking 300 mg of standardized horse chestnut seed extract by mouth can reduce some symptoms of poor blood circulation, such as varicose veins, pain, tiredness, swelling in the legs, itching, and water retention.In all trials the extract was standardised to escin, which is the main active constituent of horse chestnut seed extract. Overall, the trials suggested an improvement in the symptoms of leg pain, oedema and pruritus with horse chestnut seed extract when taken as capsules over two to 16 weeks.
What would happen if I ate a horse chestnut?
Sweet chestnuts are edible, but horse chestnuts are poisonous. If eaten, they can cause digestive problems such as abdominal pain, nausea, vomiting and throat irritation. Horse chestnut is a herb used in dietary supplements primarily for complications of venous insufficiency. Clinically significant acute liver injury has been very rarely associated with its use.Horse chestnuts contain a toxin called saponin aesculin that makes all parts of these trees poisonous. This toxin isn’t absorbed very well, so it tends to produce mild to moderate symptoms when people eat horse chestnuts. The most common symptom is stomach irritation.In addition, people with kidney or liver disease should not take horse chestnut as it may exacerbate symptoms of their disease ( 3 ). For these reasons, always consult with your healthcare provider before taking horse chestnut extract — especially if you have a medical condition or are currently taking medications.
What are the side effects of chestnuts?
Chestnuts may cause allergic reactions (hives, itching, swelling), digestive issues from high fiber content (gas, bloating), and serious toxicity if horse chestnuts are consumed raw. Horse chestnut extracts used for varicose veins may cause dizziness, headaches, and gastrointestinal upset. Horse chestnut is a seed extract. One of its active components is aescin, which may reduce inflammation and increase vein tone. It also reduces the release of enzymes that typically increase with chronic vein diseases. Other compounds in horse chestnut generally improve blood vessel tone.Horse chestnut extract appears to impair the action of platelets (important components of blood clotting). It also inhibits a range of chemicals in the blood, including cyclo-oxygenase, lipoxygenase and a range of prostaglandins and leukotrienes. These effects result in reduced inflammation and reduced blood pressure.Because horse chestnut can thin the blood and affect kidney function, it should not be mixed with: Lithium: It can interfere with how the body excretes this medication. Blood Thinners (Anticoagulants): Taking it alongside drugs like Warfarin or Aspirin increases the risk of bruising and internal bleeding.Based on reports of worsening kidney function in people with kidney disease who received intravenous aescin, horse chestnut should be avoided by anyone with kidney disease. People with liver disease should also avoid the use of horse chestnut. There are no known reasons to avoid horse chestnut during pregnancy.
