Full Spectrum CBD Oil with THC | Organic Tinctures | True Hemp Science

Whole-plant hemp tinctures crafted for people who want more than basic CBD. Our full spectrum oils preserve the complete cannabinoid family, CBD, CBDa, THCa, D9THC, and CBG, along with naturally occurring terpenes and flavonoids. The result is real entourage-effect hemp the way nature intended it, not isolated or stripped-down.

Our Full Spectrum CBD Oil Collection

Every tincture in this collection is extracted from organically grown hemp, formulated to a specific wellness purpose, and tested by independent laboratories before it reaches you. No filler cannabinoids. No artificial flavors. Just the whole plant, done right.

What Is Full Spectrum CBD Oil?

Full spectrum CBD oil is extracted from the whole hemp plant, flowers, leaves, and stalks, using methods that preserve the plant's complete chemical profile. Unlike CBD isolate (pure CBD only) or broad spectrum (CBD with THC removed), full spectrum oil keeps every naturally occurring cannabinoid, terpene, flavonoid, and plant compound intact.

That completeness matters. Scientists call it the entourage effect: the theory, supported by growing research, that cannabinoids and terpenes work synergistically, each amplifying the effectiveness of the others. THC and CBD together, for example, may reduce some of THC's anxiety-inducing properties while increasing CBD's analgesic potential. CBDa alongside CBD may offer anti-nausea and anti-inflammatory properties not found in either compound alone.

At True Hemp Science, we go further than most. We offer full spectrum oils at different stages of decarboxylation, some preserving raw acidic cannabinoids (CBDa, THCa), some partially activated, some fully decarboxylated. Each interacts differently with your body's endocannabinoid system. That's not something you'll find from a mass-market CBD brand.

Why True Hemp Science?

Since 2015, we've been making full spectrum CBD oil in Austin, Texas, not reselling someone else's. Here's what separates us:

Global organic sourcing. We hand-select hemp from biodynamic and certified organic farms in Southern Oregon, Colorado, West Virginia, and Europe. Every source is chosen for terpene richness, cannabinoid density, and farming practices, not price.

Multiple extraction methods. Sub-critical CO₂, organic grape alcohol, Spagyric triple reconstitution, and full distillation. We choose the extraction method that best preserves the specific cannabinoid profile each formula requires, not the cheapest or fastest option available.

Variable decarboxylation. We intentionally vary how much we heat our hemp. Raw products preserve CBDa and THCa. Partially activated products sit in between. Fully decarboxylated products deliver CBD and D9THC in their final form. Different levels interact differently with your endocannabinoid system, we give you the full range.

Third-party lab tested, every batch. Every product ships with a Certificate of Analysis from an independent laboratory verifying cannabinoid content, terpene profile, and the absence of pesticides, heavy metals, and residual solvents.

Award-winning in our own backyard. Named Best CBD by Austin Fit Magazine 2025. We're not a national brand manufacturing local credibility, we are genuinely from Austin.

30-day money-back guarantee. If your first order doesn't meet your expectations, we'll make it right. No forms, no hassle.

Real people, real expertise. Our founders carry decades of experience in farming, ranching, herbology, and superfood production. When you visit our South Austin store or call us, you speak to someone who actually makes the products.

Our hemp comes from: Southern Oregon (terpene-rich biodynamic hemp) · Colorado (high-altitude organic flower) · West Virginia (Appalachian whole-plant extract) · Europe (EU-certified organic hemp)

How to Use Full Spectrum CBD Oil

The sublingual method (recommended) Place your drops directly under your tongue using the dropper. Hold there for 60–90 seconds before swallowing. The sublingual mucosa absorbs cannabinoids directly into the bloodstream, bypassing first-pass liver metabolism and producing effects within 15–30 minutes.

Starting dose If you're new to full spectrum CBD oil, start conservatively: 5–7 drops once daily for the first week. Your endocannabinoid system needs time to respond and calibrate. Most people find their ideal dose within 2–3 weeks of consistent daily use.

Stacking products Many customers use multiple tinctures across the day: CBG Oil in the morning for clarity, SOLARA 19 through the afternoon for focus and recovery, and REPOSA 77 in the evening for wind-down. Our team can help design a protocol for your specific goals, just reach out.
