Scutellaria lateriflora

Scutellaria lateriflora is a biology topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Scutellaria lateriflora rather than just read about it. In short: Scutellaria lateriflora, (commonly "blue skullcap", "mad dog skullcap", "American skullcap", "side-flowering skullcap", etc.) is a hardy perennial herb of the mint family, Lamiaceae, native to North America. It has an upright habit, growing 60–80 cm (24–31 inches) in maximum height.

Key takeaways

Scutellaria lateriflora belongs to biology; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Scutellaria lateriflora to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Scutellaria lateriflora from memory before moving on to harder problems.

Reference excerpt

Scutellaria lateriflora, (commonly "blue skullcap", "mad dog skullcap", "American skullcap", "side-flowering skullcap", etc.) is a hardy perennial herb of the mint family, Lamiaceae, native to North America. It has an upright habit, growing 60–80 cm (24–31 inches) in maximum height. It is a wetland-loving species and grows near marshes, meadows, and other wet habitats. The blue flowers are just under 1 cm (0.4 inches) long. Most of the flowers do not appear at the top of the main stem but are produced along the length of side branches that grow from the leaf axils. Other skullcaps (Scutellaria) species include common skullcap (S. galericulata), western skullcap (S. canescens), and southern skullcap (S. cordifolia).

Phytochemicals

The principal phytochemicals are polyphenols in the leaves, stems, and roots of some Scutellaria species, including baicalin, baicalein, wogonin, and oroxylin A. Other constituents include lateriflorin, melatonin, serotonin, viscidulin III-2'-O-glucoside, Chyrin-6-C-ara-glc, trans-verbascoside, viscidulin, trans-martynoside, oroxylin A-7-O-glc, wogonoside, chitin, and scutellarin. Scutellaria lateriflora contains flavonoids. One study identified 5,6,7-trihydroxy-2'- methoxyflavone and its 7-O-glucuronide. Scutellarin is a flavone found in S. lateriflora and S. barbata. It is transformed by hydrolysis into scutellarein. Genkwanin, hesperetin, quercetin, rutin, naringenin, chrysin, and daidzein are the flavonoids found in S. lateriflora. The flavonoids are readily extracted using hot water. The oil from S. lateriflora contains τ-cadinene, calamenene, β-elemene, α-cubebene, and α-humulene.

Traditional uses and research Its extracts are used in herbal medicine intended as a mild sedative and sleep promoter. Cherokee women have used it as an emmenagogue. In 1773, Scutellaria lateriflora became a common treatment in North America for the hysteria and hydrophobia caused by rabies. Skullcap products have been analyzed, with some adulterated by Teucrium canadense or T. chamaedrys, also known as germander, which contains potentially hepatotoxic diterpenes.

Worked examples

Example 1 — a first encounter with Scutellaria lateriflora

Start with the simplest possible case. Write down what Scutellaria lateriflora claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Scutellaria lateriflora before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Scutellaria lateriflora ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Scutellaria lateriflora

In research: Scutellaria lateriflora appears in biology research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Scutellaria lateriflora in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Scutellaria lateriflora is common in secondary-school and first-year university syllabi. It links to neighbouring topics Anxiolytics, Botanical taxa named by Carl Linnaeus, Dopamine reuptake inhibitors, so understanding it makes those chapters shorter.
In everyday life: Look for Scutellaria lateriflora outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
