Below is general information about the safety of the known ingredients contained in the product Montana YewTip Tincture. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
LIKELY UNSAFE ...when used orally (6,18). All parts of the yew plant are considered poisonous (5604). Ingestion of 50-100 grams, or 0.6-1.3 grams/kg, of yew needles can cause death (18,5604,105514,105515). Yew can cause severe gastrointestinal irritation and can cause the heart to beat dangerously slow, fast, or irregularly (17,159,5604,86746,86756,100036,100037,100038,100039,100040,105514,105515). Many of the reported fatalities have occurred after ingestion of large amounts of plant material, especially yew needles (5603,5604,5605,86755,86756,86758,86763,100037,100041,105514,105515).
CHILDREN: UNSAFE
when the berries or needles are used orally.
One chewed berry is potentially lethal (159). Ingesting the berries or needles can cause the heart to beat dangerously slow or fast (86753,86760).
PREGNANCY AND LACTATION: UNSAFE
when the needles are used orally.
Yew needles have been used as an abortifacient (16,18).

General ...Orally, symptoms of yew poisoning include queasiness, dry mouth, (18) vomiting, vertigo, severe abdominal pain, weakness (5604,5605,100036,100037,100038,100039,100040,105514,105515), nervousness, trembling, dyspnea, incoordination (5603), tachycardia, bradycardia, arrhythmias, ventricular fibrillation, hypotension, unconsciousness, coma (5604,86746,86756,100036,100038,100039,100040,105514,105515), dizziness, seizures (100038,105514), respiratory depression (100037), mydriasis, reddening of the lips, pale and cyanotic skin (6,18,5605), and death secondary to cardiac arrest (5604,105514,105515). Usually, gastrointestinal and neurological symptoms occur early, within 30-90 minutes, followed by cardiovascular symptoms and death within 24 hours (100038,105515). Some people are allergic to yew following airborne exposure (86745,100014).
Cardiovascular
...Orally, symptoms of yew poisoning include tachycardia, bradycardia, arrhythmias, hypotension, ventricular fibrillation, and death due to cardiac arrest (5604,86746,86756,100036,100038,100039,100040,105514,105515).
Usually, gastrointestinal and neurological symptoms occur early, within 30-90 minutes, followed by cardiovascular symptoms and death within 24 hours (100038,105514,105515).
Treatment is usually related to supportive care, however, arrhythmias are often resistant to standard pharmacologic treatments and transvenous or external pacemakers (100040,105514,105515). Lipid emulsion therapy and digoxin-binding antibodies have also been used to treat yew poisoning, but the effects are unclear (105514). Veno-arterial extracorporeal membrane oxygenation (VA ECMO) has been used as a bridge during taxine elimination and cardiac recovery (100039,100040,105514). VA ECMO has typically been used for 72 hours or less (105514).
Dermatologic ...Orally, symptoms of yew poisoning include reddening of the lips and pale and cyanotic skin (6,18,5605).
Gastrointestinal ...Orally, initial symptoms of yew poisoning include queasiness, dry mouth, (18) nausea, vomiting, and severe abdominal pain (5604,5605,100036,100037,100038,100039,100040,105514,105515). Usually, gastrointestinal and neurological symptoms occur early, within 30-90 minutes, followed by cardiovascular symptoms and death within 24 hours (100038,105515).
Immunologic ...There is at least one known case of a patient with yew allergy associated with airborne exposure to yew trees (100014). Based on this case report, it was also determined that people who are allergic to yew might become hypersensitive to docetaxel, which is derived from yew (100014). Pollen from yew has caused nasal allergy in 18 patients (86745).
Neurologic/CNS ...Orally, symptoms of yew poisoning include vertigo, weakness (5604), nervousness, trembling, loss of coordination (5603), unconsciousness, coma (5604,100036,105515), dizziness, seizures (100038,105514), respiratory depression (100037), and mydriasis (6,18). Usually, gastrointestinal and neurological symptoms occur early, within 30-90 minutes, followed by cardiovascular symptoms and death within 24 hours (100038,105515).
Pulmonary/Respiratory ...Orally, symptoms of yew poisoning include dyspnea (5603).
