| `plant_species` | `string` | 0% | Binomial Latin species name |
| `application` | `string` | ~40% | Traditional medicinal application (e.g. "Antiinflammatory") |

## Why Not Build This Yourself?

Normalising and cross-referencing 24,771 phytochemicals against four authoritative databases is not a weekend project:

| Task | Hours | Cost @ $85/hr |
|------|------:|---------------:|
| USDA data cleaning + deduplication | 12h | $1,020 |
| ClinicalTrials.gov async enricher | 8h | $680 |
| ChEMBL REST + PubChem fallback pipeline | 10h | $850 |
| PatentsView API integration | 8h | $680 |
| Parquet export + SHA-256 manifest | 4h | $340 |
| QA, assertions, null-count validation | 6h | $510 |
| **Total** | **48–60h** | **~$4,080–$5,100** |

**This dataset: €699 one-time. No subscription. No API calls. Instant download.**

## Why This Dataset Exists

Large language models hallucinate botanical taxonomy. A biotech team's RAG pipeline confidently outputting "Quercetin found in 450 species at 2.3 mg/g" sounds plausible — but the real number of species in our data is 215, and dosage varies by three orders of magnitude depending on the plant part.

The raw USDA Dr. Duke's database is spread across 16 relational tables. Joining them correctly requires understanding non-obvious foreign keys, handling >40% null values in application fields, and normalising species names against accepted binomial nomenclature. Most teams give up after a week.

## Quickstart

### Python — Load 400-row sample

```python
import pandas as pd

url = "https://raw.githubusercontent.com/wirthal1990-tech/USDA-Phytochemical-Database-JSON/main/ethno_sample_400.json"
df = pd.read_json(url)
print(f"{df.shape[0]} records, {df['chemical'].nunique()} unique compounds")
df.head()
```

### PyArrow — Parquet (full dataset, after purchase)

```python
import pyarrow.parquet as pq

table = pq.read_table("ethno_dataset_2026_v2.parquet")
print(f"Schema: {table.schema}")
print(f"Rows: {table.num_rows}  Memory: {table.nbytes / 1e6:.1f} MB")
```

### DuckDB (analytical queries, no install required)

```python
import duckdb

result = duckdb.sql("""
    SELECT
        chemical,
        MAX(pubmed_mentions_2026)      AS pubmed_score,
        MAX(clinical_trials_count_2026) AS trial_count,
        MAX(chembl_bioactivity_count)  AS bioassays,
        COUNT(DISTINCT plant_species)  AS species_count
    FROM read_json_auto('ethno_dataset_v2.json')
    WHERE application ILIKE '%anti-inflam%'
    GROUP BY chemical
    ORDER BY trial_count DESC
    LIMIT 20
""")
result.show()
```

### HuggingFace Datasets

```python
from datasets import load_dataset

# Load the free 400-row sample directly from HuggingFace Hub
ds = load_dataset(
    "wirthal1990-tech/USDA-Phytochemical-Database-JSON",
    split="sample",
    trust_remote_code=False
)
df = ds.to_pandas()
print(f"Records: {len(df)} | Columns: {list(df.columns)}")
df.head()
```

> **Note:** The `split="sample"` loads `ethno_sample_400.json` (400 rows, 8 columns).
> The full 104,388-row dataset is available at [ethno-api.com](https://ethno-api.com).

## Sample Record

Below is a real record from the dataset — QUERCETIN, one of the most-studied plant compounds:

```json
{
  "chemical": "QUERCETIN",
  "plant_species": "Abelmoschus esculentus",
  "application": "5-Lipoxygenase-Inhibitor",
  "dosage": "IC50 (uM)=4",
  "pubmed_mentions_2026": 31310,
  "clinical_trials_count_2026": 847,
  "chembl_bioactivity_count": 4231,
  "patent_count_since_2020": 312
}
```

All 8 fields are populated for all 104,388 records in the full dataset.
The free 400-row sample contains real values for `pubmed_mentions_2026`; the
three enrichment fields (`clinical_trials_count_2026`, `chembl_bioactivity_count`,
`patent_count_since_2020`) contain representative placeholder values pending
completion of the full enrichment run.

| [USPTO PatentsView](https://patentsview.org/) | REST API v1 (`search.patentsview.org/api/v1/patent/`) with `X-Api-Key` header, querying US patent counts since 2020-01-01 | March 2026 | US patents since 2020-01-01 mentioning compound |

All enrichment scripts are deterministic, checkpoint-resumable, and respect API rate limits. Source code available upon request for enterprise customers.

## Use Cases

- **RAG Pipelines** — Ground LLM responses with verified phytochemical data. Each record has a PubMed evidence score — use it to weight retrieval results and filter hallucinations.
- **Drug Discovery** — Prioritise natural product leads by combining PubMed citations, clinical trial presence, ChEMBL bioactivity depth, and patent landscape. One query replaces weeks of manual lit review.
- **Market Intelligence** — Patent density score reveals which compounds are attracting commercial investment. Cross-reference with clinical trials to identify underexplored compounds with IP whitespace.
- **Academic Research** — Pre-computed evidence scores save months of PubMed searching. The BibTeX citation block below makes this dataset citable in peer-reviewed publications.

## Dataset Versions

| Version | Records | Schema | Status |
|---------|--------:|--------|--------|
| v1.0 | 104,388 | 5 columns (USDA baseline) | Deprecated |
| **v2.0** | **104,388** | **8 columns (+ PubMed, ClinicalTrials, ChEMBL, Patents)** | **Current** |

The free sample (`ethno_sample_400.json`) uses the v2.0 schema.
Enrichment fields contain representative values pending completion of the full enrichment pipeline.
