Tincture
open-in-new
<h2 id="characteristics">Characteristics</h2> <p>Tinctures are often made of a combination of <a href="/facts/Ethanol/3lCLfBSP">ethyl alcohol</a> and water as solvents, each dissolving constituents the other is unable to, or weaker at. Varying their proportions can also produce different levels of constituents in the final extraction. As an <a href="/facts/Antimicrobial/80ECEmvP">antimicrobial</a>, alcohol also acts as a preservative. </p><p>A downside of using alcohol as a solvent is that ethanol has a tendency to <a href="/facts/Denaturation_(biochemistry)/Eh1hc3Bg">denature</a> some organic compounds, reducing or destroying their effectiveness. This tendency can also have undesirable effects when extracting botanical constituents, such as <a href="/facts/Polysaccharide/lqXq2cJU">polysaccharides</a>. Certain other constituents, common among them <a href="/facts/Protein/Jxmagu3E">proteins</a>, can become irreversibly denatured, or "pickled" by the alcohol. Alcohol can also have damaging effects on some aromatic compounds. </p><p>Ether and <a href="/facts/Propylene_glycol/vVGdx32R">propylene glycol</a> based tinctures are not suitable for internal consumption, although they are used in preparations for external use, such as personal care creams and <a href="/facts/Ointment/alFfLndS">ointments</a>. </p> <h2 id="examples">Examples</h2> <p>Some examples that were formerly common in medicine<a class="footnote-ref" id="fnref:4" href="#fn:4"><sup>4</sup></a> include: </p> <ul><li><a href="/facts/Tincture_of_benzoin/t6pFB8ro">Tincture of benzoin</a></li> <li><a href="/facts/Tincture_of_cannabis/hLpsLqS0">Tincture of cannabis</a></li> <li>Tincture of <a href="/facts/Cantharidin/vXGFx022">cantharides</a></li> <li>Tincture of <a href="/facts/Castoreum/SFTTFDm5">castoreum</a></li> <li>Tincture of ferric citrochloride, a <a href="/facts/Chelate/4G79sXBB">chelate</a> of <a href="/facts/Citric_acid/EgKGQBdl">citric acid</a> and <a href="/facts/Iron(III)_chloride/a51pulq1">Iron(III) chloride</a></li> <li>Tincture of green <a href="/facts/Soap/99DbjMR5">soap</a>, which classically contains <a href="/facts/Lavender/WGnWX9Rh">lavender</a> oil</li> <li>Tincture of <a href="/facts/Guaiacum/vhuR2Yyb">guaiac</a> gum</li> <li><a href="/facts/Tincture_of_iodine/BtmHsmpD">Tincture of iodine</a></li> <li>Tincture of <a href="/facts/Opium/JzHUtced">opium</a> (<a href="/facts/Laudanum/2J5jqNmu">laudanum</a>) <ul><li><a href="/facts/Camphor/53KvP2Rw">Camphorated</a> tincture of opium (<a href="/facts/Paregoric/dmdEU2sK">paregoric</a>)</li></ul></li> <li>Tincture of <a href="/facts/Mentha_pulegium/S7C3AY06">pennyroyal</a></li> <li><a href="/facts/Warburg%2527s_tincture/wQU8kfRz">Warburg's tincture</a> ("Tinctura Antiperiodica" or "Antiperiodic Tincture", a 19th-century <a href="/facts/Antipyretic/lBVzyUFN">antipyretic</a>)</li></ul> <p>Examples of spirits include: </p> <ul><li>Spirit of <a href="/facts/Ammonia/MtLtJFtz">ammonia</a> (<a href="/facts/Spirits_of_hartshorn/IDkHUJaQ">spirits of hartshorn</a>)</li> <li>Spirit of <a href="/facts/Camphor/53KvP2Rw">camphor</a></li> <li>Spirit of ether, a solution of <a href="/facts/Diethyl_ether/Ep20vEdj">diethyl ether</a> in alcohol</li> <li>"Spirit of Mindererus", <a href="/facts/Ammonium_acetate/bs2fv321">ammonium acetate</a> in alcohol</li> <li>"Spirit of <a href="/facts/Nitre/vVeaDn51">nitre</a>" is not a spirit in this sense, but an old name for <a href="/facts/Nitric_acid/UDbwGp6s">nitric acid</a> (but "sweet spirit of nitre" was <a href="/facts/Ethyl_nitrite/me7nBARc">ethyl nitrite</a>)</li> <li>Similarly "spirit(s) of salt" actually meant <a href="/facts/Hydrochloric_acid/HqItJlUT">hydrochloric acid</a>.
