Kucera 2005, PLANTS 2017, Stickel 2000 HistoryĬomfrey has been cultivated in Japan as a green vegetable and has been used as an herbal medicine for more than 2,000 years. asperum, and has been cultivated to contain insignificant amounts of alkaloids in the aerial parts of the plant. It grows to heights of 50 to 150 cm and has long, hairy lanceolate leaves and bell-shaped, red-violet or yellowish flowers. Scientific FamilyĬomfrey is a perennial plant found in moist grasslands in western Asia, as well as in North America. Comfrey is generally considered unsafe, with numerous toxicological effects in animals and humans. The Food and Drug Administration (FDA) released an advisory in July 2001 recommending that comfrey products be removed from the market because of cases of hepatic veno-occlusive disease. Infants are more susceptible to pyrrolizidine-related, veno-occlusive disease therefore, the use of comfrey in this population is contraindicated. Case reports show hepatic veno-occlusive disease and pulmonary hypertension related to comfrey use. Neither internal nor extensive topical use of comfrey is recommended because of numerous reports of liver toxicity (see Toxicology). Animal experiments have detected alkaloids in breast milk. Pyrrolizidine alkaloids have abortifacient effects and increase the risk of fatal hepatic veno-occlusive disease. Pregnancy/LactationĬontraindicated because of documented adverse effects. Use is contraindicated during pregnancy and lactation, in infants, and in patients with liver or kidney disease. Patients with hypersensitivity or allergic reactions to the plant should avoid external use. ContraindicationsĬomfrey is not recommended for internal use because of the hepatotoxic pyrrolizidine alkaloid content. Limited trials have evaluated the efficacy of alkaloid-free preparations for topical use however, these studies do not report on hepatic laboratory indices of study participants. Additionally, because externally applied alkaloids are well absorbed and detected in the urine, topical use of comfrey should not exceed an alkaloid exposure of 100 mcg/day. Oral use of comfrey is not supported because of potential hepatotoxicity. Although not examined in clinical trials, comfrey may possess antifungal and anticancer activity. A limited number of clinical trials show short-term efficacy of topically applied, alkaloid-free comfrey preparations in skin abrasions and inflammatory conditions. Therapeutic use of comfrey is limited because of its toxicity. tuberosum L., Symphytum officinale L., Symphytum x uplandicum NymanĬommon Name(s): Blackwort, Bruisewort, Comfrey, Knitbone, Radix consolidate, Russian comfrey, Slippery root, Symphyti radix Tasmanian Herbarium, Tasmanian Museum and Art Gallery, Hobart.Scientific Name(s): S.

Simulate this circuit – Schematic created using CircuitLab I've come across this answer on stack exchange and I now can better understand sphero's and AnalogKid's answers. It's still a bit unclear to me if Q2 is supposed to be saturated (and act as a switch) or in the active region (and boost the current gain of the Darlington pair). The gain of the "high-current triple" formed by Q2, Q3 and Q4 is gigantic and as such any leakage current from Q1 (EM interference, stored charge or otherwise) might turn on the LEDs unwantedly. R3, R4 and R5 are high-valued resistors that discharge the base-emitter capacitance and insure a quick turn-off. The Darlington pair formed by Q3 and Q4 must be driven high-side, hence the use of Q2. The constant current source is used to "absorb" the variations in supply voltage. The purpose of the circuit is to ensure as big as possible of an output current, not a constant current. How would I go about analyzing the functioning of the PNP transistor and can I determine the values of the currents passing through it?Īs it stands, my current understanding of the circuit is: But the presence of the high-value resistor R3 confuses me as I don't see any clear purpose for its presence, perhaps to help with biasing the PNP? I was thinking that it exists to push current from its base to the collector of the transistor Q1 and that the whole PNP and Darlington section of the circuit acts as an active load for the constant current source centered on Q1. I understand most of the circuit's workings but I fail to understand why the PNP transistor exists.

Spray it on, spread it around and give it five minutes to soak into the tape. If it' still not working, and if you're using paper transfer tape (not clear), you can moisten the back of the tape with application fluid to soften the tape's adhesive and weaken the bond between the tape and the vinyl. Use good firm squeegee pressure to press the film onto the wood and, if it's not sticking, give it up to 20 minutes to set before you try to remove the tape. This is more common with acrylic adhesives. This is not necessarily a sign of failure. Sometimes when you remove the transfer tape, the letter come up with it. If you're having trouble, try a different kind of vinyl, or purchase one with a solvent-based adhesive to give yourself the best chance of success.Įven when you have everything right, sometimes the challenges of the porous substrate make it hard for the vinyl's adhesive to bond or 'wet out' quickly. Solvent based adhesives are a little more effective on porous or less than ideal surfaces like wood and stainless steel. You can read the full story in our Adhesives 101 article, but the short summary is this. There are differences in the performance of acrylic and solvent-based adhesives that can affect adhesion to non-standard substrates. This is often a precursor for eventual adhesive failure.įor more tips about suitable substrates, visit and read the FAQ. Trapped VOCs can also cause bubbles to appear under the vinyl. This can cause adhesive failure after application. Fresh paint emits VOCs (volatile organic compounds) that may react chemically with the vinyl's adhesive and degrade it. Make sure if you're putting vinyl on any painted surface that the paint is completely cured. If you can't find One Shot, try an enamel paint. The best paints to use are those developed for sign making, like 1 Shot brand. There are two things to watch out for porous paints that won't make a good seal with the adhesive, and uncured paint. How to Make it Work BetterĪnother question we hear often is about what kind of painted substrates are suitable. If you absolutely must use unsealed wood for your vinyl graphics, keepsake, or bit of rustic restaurant decor, sand it first to get it as smooth as possible. But If you choose MDO, please make sure it’s properly prepared and painted. MDO plywood composite is also a commonly used sign substrate. There are different trade names for these, but if you look for Alumacore, Alumalite, or DIBOND®, you’ll be able to find a reliable substrate for long term outdoor signage. These products are comprised of a sheet of aluminum laminated to a thick, flex resistant core made of a corrugated composite or plastic product. The most compatible options will be aluminum composite materials. For larger graphics, heavier substrates are required. The vinyl may stick initially, but sooner or later (probably sooner), it's going to come off.įor long term outdoor graphics, the smooth substrates mentioned above are the best choice. Rough surfaces like unfinished wood will not provide a sufficient bond with the adhesives used on vinyl films. This requires the use of very smooth substrates like glass, corrugated plastic, foam core, and painted aluminum. To achieve that longevity, the adhesive must have a firm bond with the substrate. Vinyl is an adhesive backed film that is expected to last for years outdoors in all kinds of weather. Wood is not the best choice for VinylĪctually unsealed wood, plywood and even painted plywood are not good substrates for vinyl. But there are ways to make it work and things to avoid. When vinyl doesn't stick to wood, the problem is usually with the wood. As the old Porgy and Bess song says, "It ain't necessarily so". Many people call asking why their vinyl won't stick to the wood and assume there's a defect with the vinyl. As craft and hobby vinyl enthusiasts discover the appeal of rustic substrates, we receive more questions about putting vinyl on wood blanks. One of the most frequently asked questions we receive deals with substrates. |
